Candidate #2: Kanye West, the Foot-in-Mouth Professional
I think for all parties involved, it would be best if Kanye took a moment before opening his mouth and thought, "Would Barack Obama call me a jack**s if I said this?" Maybe that would save him from the repeated viewing on YouTube of his embarrassingly inappropriate interruption of Taylor Swift's acceptance speech at the VMAs. Or just give up talking entirely. And typing. Fortunately, his word vomit inspired an amazing web meme of Kanye interrupting just about every moment in history. Keep the funnies coming, Internet.
