Paul Rudd seems like a guy who's up for anything. His sense of humor--as can be seen in "Anchorman"--is just as silly as, say, Jimmy Fallon's, so when the two get together you know something good is going to happen.
Fallon kept up the momentum of his first week at "The Tonight Show" with a lip sync battle, allowing Rudd to go first since he was the guest. Rudd, who isn't afraid to look silly in order to get a laugh, decided to pick a Tina Turner song to kick things off and really got into it, working the microphone and throwing hand gestures out for the full effect.
Fallon followed that up with "Jukebox Hero" by Foreigner, which worked the crowd into a frenzy. Watch the entire battle below.
