Zach Galifianakis

Actor and comedian Zach Galifianakis is best known for his shaggy red beard and his hilarious role in the bachelor-party comedy The Hangover. He tells Terry Gross how he prepared himself for his latest part -- a dramatic role as a mental patient in the film It's Kind of a Funny Story.

The comic, who plays a rodeo clown in his new FX comedy series, says he is "not creeped out by clowns." Galifianakis is also the creator of the Emmy Award-winning web comedy series Between Two Ferns.
