Joe Biden Accidentally Thanks Dr Pepper During Campaign Speech (VIDEO)

If Barack Obama is the cool dad of politics, then his Vice President Joe Biden is definitely the goofy uncle. Gaffing his way around America as a part of the Obama 2012 campaign, his latest slip-up involved a particular brand of carbonated soft drink: Dr Pepper.

What he meant to say during his Iowa speech was "Thank you Dr. Paper" - because Dr. Teresa Paper is the new President for Scott Community College, where the speech took place.

And though it's not the biggest blooper in the world, it's definitely one of many. Just take a look at this Biden cock-up collection we've got for you below, and prepare to wince as he asks a man in a wheelchair to stand up. Several times.
