Yesterday Michael Cera and Jason Schwartzman had us laughing at their antics on the morning weather report, and today we have another bizarre publicity stunt from the two "Scott Pilgrim Vs. The World" stars. When Matt Zaller sat down to interview Cera and Schwartzman about their movie, he didn't expect to get an uninvited guest, especially not Zach Galifianakis. Not only is Galifianakis not even in "Scott Pilgrim," but he completely interrupts the interview (although based on the topic being obscure Beatles lyrics, it didn't seem to be going anywhere anyway). So due to lack of footage, Zaller turned this funny video-bomb into an auto-tuned song featuring all three funny men.
