Eddie Vedder and Jimmy Fallon ‘Balls in Your Mouth’

Pearl Jam frontman Eddie Vedder became the latest iconic rock star to team up with Jimmy Fallon in a goofy musical bit on last night's episode of Late Night. In this skit, Fallon introduces a protest song he's written about the BP oil spill from last year, but as it goes along and Vedder joins in, the lyrics seem to take on a very different meaning.
