20 Stunts by Funny People

Judd Apatow's new film 'Funny People' opens in theaters on July 31, and to help ring that film in right, I've amassed this slideshow of, well, funny people doing funny things.

From appearances by seasoned comedians (like Jerry Seinfeld's ads for Microsoft) to more unexpected funny people (Michael Phelps on 'Saturday Night Live'), this cluster has all you need to get your giggles flowing.
