OK, I had to wait all day for Mark to post this to MeShow, and he finally has. It's basically the dance mix of lunatic playing Counterstrike. There's more info on Mark's site. Be warned, this mp3 is extremely profane, but then again that only makes it funnier. OBTW, it's a 4.8MB download.

Update 10:26PM: OK I listened to The Terrible Mr. Grimshaw again... did I mention this is really profane? You will hear several naughty words... a lot... really. You've been warned.
