Watch: Jamie Foxx recalls mocking Mike Tyson to his face

Jamie Foxx made fun of Mike Tyson's lisp to his face and lived to tell the tale.

Appearing on "The Tonight Show Starring Jimmy Fallon," Foxx recalled how, early on in his stand-up career, he started telling a joke about Tyson going through a KFC drive-thru without realizing the boxer was at the comedy club that night. Tyson gave him permission to do the joke, and, fortunately for Foxx, found it funny.

Foxx confirmed earlier this year that a Tyson biopic "is a go," with both his and Martin Scorsese's names attached to the project.
