Went on an unsuccessful "Harold and Kumar meets Dude, Where's My Car?" style adventure with my band yesterday, but the whole shebang ended with me and my drummer playing Guitar Hero 2 over some drinks and I realized how much I love the song "Who Was In My Room Last Night?" by Butthole Surfers. My drummer said he hadn't really listened to song except to pass it in the game, but once he heard me complete it, the riff got stuck in his head. 'Twas a bonding moment.
I'll admit, I'm terrible at Guitar Hero (I'm a bass player, so I have trouble with the chording bits), but we've started playing it as a band because it really tightens up your sense of timing.
The video is pretty gnarly too. http://www.youtube.com/watch?v=GP7R7aUYCz0
