After talking about his new movie While We’re Young and confessing how not cool he is, Ben Stiller proved he's actually the illest motherfucker from here to Gardenia. Seth Myers used Ad-Rock's (Adam Horovitz) role in the film to segue into Stiller's Beastie Boys fandom and to further segue into a quick round of lyrics trivia. Stiller absolutely nailed it, going 4/4.
No wonder he got to perform with the Brooklyn trio.
