Will Ferrell Has A Filthy Potty Mouth

When we met up with the comic superstar during the MTV Sneak Peek Week screening of "The Foot Fist Way," he had some choice words for us. More specifically, the "Step Brothers" star's enthusiasm for the Movie Awards caused him to cuss like a sailor. You can check out the resulting shenanigans below, though you might want to cover your ears.

The MTV Movie Awards will air live on MTV on Sunday at 8 p.m. ET, with MTV News' "Coming Attractions" preshow kicking the evening off at 7:30 p.m. ET! Meanwhile, stay tuned to the MTV Movies Blog and MovieAwards.MTV.com.
