My wife has been trying to get me to listen to a song called "Code Monkey" from someone named Jonathan Coulton. I didn't have any idea who he was, but somehow today I ended up at his website listening to a song called Chiron Beta Prime. It's a free download from his website, and it cracked me up. Nothing like a Christmas song with robots. Anyway, check out his site, and buy his music.
Addendum: Code Monkey is pretty awesome too. As is this video:
