What’s everyone else’s favorite Game Changer/MSN karaoke song?

I just remembered the brilliance that is Slip 'n' Slide by The Beastie Boys and I'm so curious what everyone else's favorite fake karaoke song is. (By the way, that one's in a three way tie for me with To Do List by The Supremes and, of course, The Story of Sisyphus by Tom Waits.)
