The Singing Keyboard prank

This hack isn't really rocket science, and it's not really a showstopper either, but it does provide the opportunity to cause a mild amount of annoyance to a coworker for relatively low cost and hassle -- how do you beat that? It's all explained over at The Mozmonkey Blog, who prefaces his hack as a potentially "career-limiting move," and then goes on to show how to use the musical part from a musical greeting card to rig a keyboard to make loud annoying music whenever the caps lock is in use. We're told that hijinks ensue, but really, unless we decide to keep slogging through "The Elder Scrolls IV: Oblivion" this weekend, what else are we supposed to do this afternoon?
