Weird Al Yankovic is best known for spoofing famous songs ('Fat,' 'Amish Paradise' and 'It's All About the Pentiums' are some of our favorites), but he's also written and starred in movies and television shows. ('UHF,' FTW.) When he isn't doing all that, however, he apparently wanders the hallowed halls of Pixar studios. At least according to this photo tweeted by director Lee Unkrich ('Toy Story 3,' 'Finding Nemo'), which the weird one confirmed this on his Twitter account. So what is Weird Al doing at Pixar? Allow Moviefone to offer some guesses.
