PUEBLO, Colo. -- It's rare that an audience asks the famously audible Joe Biden to speak up.

But with the acoustics in Pueblo's Central High School gymnasium leaving many of the thousand attendees at his Saturday afternoon rally unable to hear him, they did.

"I wish to hell they'd turn this mic up!" an annoyed Biden declared loudly upon hearing their pleas for more volume.

Biden, who is known to read media coverage of his slip-ups and frequently notes in front of audiences that he "got in trouble" with the press for mistakes,  joked about the kind of headlines that the sound situation could garner as he belted out the remainder of his remarks.

"I'm going to hear a press report," he said as the audience giggled at his imagined headline. "'Biden screamed at the audience.'"

ARVADA, Colo. -- Ka-zing.

Three days before the election, Vice President Joe Biden pegged his newest critique of Republican presidential nominee Mitt Romney to the semi-annual inconvenience of adjusting clocks for Daylight Savings Time, which occurs tonight.

"It’s Mitt Romney’s favorite time of the year -- because he gets to turn the clock back!" Biden told a crowd of hundreds at a suburban Denver high school.

In his remarks, the vice president accused Romney of embracing social policies out of an earlier era, pointedly noting the GOP nominee's voiced enthusiasm for "getting rid of" Planned Parenthood. 

"With all the issues facing the country, Gov. Romney has focused on for the last three months [that] he's going to get rid of Planned Parenthood" Biden said. "And by the way, he doesn't even know he doesn't control Planned Parenthood."

"He should talk to Big Bird!" he added, referencing the scuffle over public broadcasting funding that broke out during one of the presidential debates.

(In context, Romney said last spring he was going to "get rid" of federal funding for Planned Parenthood, not get rid of the entity itself.)

Biden has two events scheduled in swing state Colorado Saturday. He will campaign Sunday in Ohio.

Love him or despise him, many Americans see Vice President Joe Biden as an occasional source of comedic relief - whether he intends it or not.

Getting a few laughs will be at least part of his role five days from Election Day, when the vice president will join the Late Show with David Letterman to read the famed "Top Ten" list.

An aide says Biden taped the segment from his Davenport, IA hotel Thursday between attending church, eating breakfast at a famed local cafe and departing for a campaign event in Muscatine.

No word yet on the topic of the list.

The comedy routine comes as both campaigns try to balance political attacks and the aftermath of a historic storm that devastated parts of New Jersey and Letterman's New York City.

It airs tonight.

SARASOTA, Fla. -- Promising to give a Sarasota audience "the whole load" of his GOP criticism, Vice President Joe Biden unloaded a barrage of derision Wednesday over a Romney campaign ad alleging that American automakers are planning to move manufacturing overseas to China.

Calling the Jeep ad "one of the most flagrantly dishonest ads I can ever remember in my political career," Biden called the allegation - which has been widely disputed by fact checkers and by the auto companies themselves - "an outrageous lie."

"All my time I have never heard an American corporation in the waning hours of the campaign engage with that kind of description of what a presidential candidate's doing," Biden said after quoting a General Motors statement calling the Romney ad "campaign politics at its cynical worst."

Responding to Biden's criticism, Romney adviser Kevin Madden said "We've got an ad out that we believe makes the case for why Gov. Romney would be stronger for the auto industry and why the auto industry's an important part of a strong economy. They've got an ad that they're using to make their case to the public, and we'll leave that with voters."

In Sarasota, Biden claimed that auto workers in Ohio have been frightened about losing their jobs because of the ad, calling United Auto Workers representatives to ask if its allegations are true.

"Folks, the president's job is not to show confusion," he said. "It's to plant the seeds of confidence."

The vice president's remarks to a crowd of over a thousand came 1100 miles away from the rust belt cities where the Romney ad is on the air, emphasizing how strongly the Obama team hopes to push back against the commercial and make its claims into a character issue for Romney. President Barack Obama is not on the campaign trail today, traveling in New Jersey with GOP governor Chris Christie to survey damage from SuperStorm Sandy.

Vice President Joe Biden made a reference to possible future political ambitions at a stop Wednesday at a restaurant in Florida.

A short while after an earlier rally -- where the vice president boasted of "being a good Biden" today -- Biden slipped into a characteristic moment, to the delight of DC's chattering class.

NBC's Carrie Dann, who is traveling with the vice president, describes the scene:

At an off-the-record stop at a restaurant called "400 station" in Sarasota, Joe Biden spoke on the phone with the brother of a voter who wanted him to chat with her Republican relative.

After chatting about the health insurance law, he concluded, "Well look, I'm not trying to talk you into voting for me, I just wanted to say hi to you, okay? And after it's all over when your insurance rates go down, then you'll vote for me in 2016. I'll talk to you later."

Biden is among the handful of Democrats included in early speculative lists of possible presidential candidates in 2016, at which point the former Delaware senator would be 73-years-old.

His viability as a candidate, though, might well hinge on the outcome of the 2012 election next Tuesday, when a second term for President Barack Obama is far from certain.

YOUNGSTOWN, Ohio -- Pushing back hard at a new ad by political opponents, Vice President Joe Biden and former President Bill Clinton accused the Mitt Romney campaign Monday of saying "absolutely anything to win" and engaging in an attack on President Obama's auto industry record that is "the biggest load of bull in the world."

The tough rhetoric comes after the Romney campaign launched an ad in Ohio claiming that ""Obama took GM and Chrysler into bankruptcy and sold Chrysler to Italians, who are going to build Jeeps in China."

Speaking to over 4,000 supporters in Youngstown, Clinton flatly decried that as "bull."

"It turns out, Jeep is reopening in China because they've made so much money here, they can afford to do it and they are going on with their plans here," he said. "They put out a statement today saying it was the biggest load of bull in the world that they would ever consider shutting down their American operations. They are roaring in America, thanks to people like the people of Ohio."

Biden, whose stump speech was even more littered with folksy appeals than usual as he shared the stage with Clinton, accused Romney of "pirouettes more than a ballerina" on his auto industry stances and called the ad "an absolutely patently false assertion."

"Ladies and gentlemen, have they no shame!?" he added. "I mean, what? Romney will say anything, absolutely anything to win, it seems."

Obama's record on the auto industry bailout is largely credited for buoying his poll numbers in swing state Ohio, a firewall Romney is eager to burn through.

Biden on Monday also accused Romney of proposing to "liquidate" the auto industry, a claim that the GOP nominee vigorously contests.

“Today, Vice President Biden falsely claimed that Mitt Romney wanted to ‘liquidate’ the auto industry, and was dishonest about the administration’s own record," said Romney spokesman Ryan Williams. "Mitt Romney’s support for loan guarantees and warranties for the U.S. auto industry is clear. The Obama campaign is less concerned with engaging in a meaningful conversation about his failed policies and more concerned with arguing against facts about their record they dislike." 

Vice President Joe Biden earned ridicule from foes Saturday when he twice referred to the Democratic Virginia Senate candidate by the wrong first name.

Biden began his remarks to an enthusiastic crowd of about 1,500 at the Lynchburg Armory by praising former Gov. Tim Kaine with the correct name but later declared two times that he is "a big Tom Kaine fan."

Kaine is running against Republican George Allen for the seat vacated by Democrat Sen. Jim Webb, who is retiring.

The vice president went on to offer similar compliments for ex-Rep. Tom Perriello, whose first name is Tom.

A Mitt Romney campaign spokesman immediately highlighted the error.

“Vice President Biden forgot the name of his own Virginia Democratic Senate nominee and he wants voters to forget about President Obama’s failed economic policies and lack of a real agenda for a second term," Ryan Williams wrote in a campaign statement.

In Lynchburg, Biden also accused Republicans of hoping for lapses of memory.

"They're counting on the American people to have an overwhelming case of amnesia on November the 6th," he said.

Obama campaign spokesperson Lis Smith also responded.

"Once again, Mitt Romney’s campaign is showing their focus on the big things — like one letter in Tim Kaine's name," Smith said. "If they put as much time and effort into their policies, maybe we'd finally have an answer for how they'd pay for $5 trillion in tax cuts weighted to the very wealthy."

Kaine, the victim of the flub, responded in a tongue-in-cheeck tweet later Saturday.

"Thanks to the VPOTUS for the shout out today. I love Jay Biden!" he joshed via Twitter.

MARION, Ohio -- Vice President Joe Biden assumed the role of jokester-in-chief on Wednesday in Ohio, alternating between a policy lecture and an amateur comedy gig in ridiculing the Republican presidential ticket.

Appearing in Ohio at the end of a three-day trip, Biden's campaign pitch offered comfort and glee for the base and occasional fodder for the opposition.

There was the assurance to a crying baby that Mitt Romney wouldn't win the election. "It's okay. He's not going to get elected," he mock-soothingly announced as a child in the audience wailed. "God, I shouldn't be scaring children like this!"

There was the groaner understandable only to aficionados of Buckeye State geography. Relating that he's traveled from the phonetic "Dayton, Ohio" to "Marion, Ohio," he cracked "I didn't think I was marrying y'all!"

And there was the slip-up quickly picked apart by Republicans familiar with Biden's occasional history of locality-based missteps. Lamenting the political ads he's seen in his travels, he said the commercials were saturating airwaves "here in Iowa." (That prompted a release from Boston offering Team Romney's "Response to Vice President Biden in Iowa ... Uh... Ohio.")

As the closing weeks of the election loom, Biden's speeches have become must-watch fodder for journalists - who often tweet highlights as they watch live video feeds from their offices - and for Biden foes eager to catch one of his famed rhetorical goof-ups.

Biden's rally of over a thousand supporters in a high school gymnasium disappointed neither.

Speaking of Romney and Ryan's tax plans, Biden related a teenage memory of wanting to hang out "on the corner" with troublemaking kids, only to be stopped by his mother's warning.

"She'd look at me and she'd say, 'Joey, if it looks like a duck, and it walks like a duck, and it quacks like a duck, it's a duck!'" he declared.

While wasn't entirely clear how Biden transitioned from effective tax rates to poultry, the crowd loved it.

"Man," he concluded. "This is one quackin' duck!"

TOLEDO, Ohio -- Continuing the argument he voiced on network morning news shows today, Vice President Joe Biden said Tuesday that GOP nominee Mitt Romney is vacillating between saber-rattling and dovishness on foreign policy.

"Last night you saw Gov. Romney rushing to agree with President Obama," Biden told a crowd of over a thousand at the University of Toledo, adding a "whoa!" for good measure.

Vice President Joe Biden gestures while speaking during at a campaign rally, Tuesday, Oct. 23, 2012, at The University of Toledo in Toledo, Ohio.

The vice president said he was "stunned and pleased that Gov. Romney had disavowed so many things he's said in the past and acknowledged that the president was right on so many things."

"Some days they go out there and rattle the sabers, some days they are doves carrying olive branches," he added. "The only thing consistent ... about the way they talk about policy is that they are inconsistent."

The argument echoes his comments to NBC's TODAY that he was "surprised" to hear so much agreement from the GOP nominee.

Biden also won cheers from the friendly crowd for knocking the Republican ticket's "foreign policy out of the 80s, a social policy out of the 50s, and an economic policy out of the 20s."

The rally coincided with the Obama campaign's new push to publicize its vision for the next four years, condensed in a glossy packet that awaited the traveling press arriving at the event. Brandishing a copy, Biden conceded that it "sounds so trite to hold up a plan" but that "it's all here" in the 20-page brochure.

Biden's next event today is a joint rally with the president in Dayton.

CANTON, OH -- Vice President Joe Biden has begun to take a different tack toward GOP presidential nominee Mitt Romney, taking aim at Romney's lurch toward the center on some issues and refusal to answer specifics on others.

Biden declared that the GOP ticket wasn't "hiding the ball" when it came to their agenda while campaigning earlier this year, but has begun to deliver a new message since the first presidential debate.

Seeking to hammer that message home in all-important swing state Ohio, Biden told a boisterous crowd Monday that "we are seeing the remaking of Mitt Romney right before our eyes."

Speaking to about 800 supporters at a Canton gymnasium, Biden cited women's rights and Afghanistan as policy areas where Romney's agenda is "etch-a-sketchy."

"This guy is out of touch on most of the fundamental issues," said Biden. "America's moved beyond where these guys are."

Biden's trip to Ohio marks his ninth visit there this year and the 23rd trip to the state of his vice presidency. He will hold five campaign rallies over three days, including a joint appearance with President Barack Obama on Tuesday.

While Biden's events are attended almost entirely by supportive and high-interest voters, they've become a barometer of how the campaign's new campaign attacks are resonating with the Democratic base. In Florida last week, voters chanted "malarkey!" in recognition of the vice president's uncorking of a favorite Irish colloquialism at the Danville debate. In Ohio Monday, supporters shouted "Romnesia!" even before Biden mentioned the new Democratic label for Romney's alleged malleability.
