Paul Rudd and Jason Segel have been tirelessly promoting their upcoming film I Love You, Man, (which looks hilarious), and you can tell they're looking for something to do other than talk about the movie.  That thing?  Farts.  They go nuts in this interview, making a great number of fart noises, leading them to laugh-til-they-cry quite literally over a very funny Jason Segel joke.  How boring must it be to interview about the same movie for months on end?
