Where did the Gnome dance come from?

Q u o t e:
Male Gnome, at least.

You've got Tunak Tunak for Draenei, Napoleon Dynamite for Blood Elves..

But what about Gnomes? I want to know particularly so I can play that particular song whenever I'm dancing on him!

A lesser known fact here -- the gnome dance actually comes from Drysc. It's the way his body moves when he becomes nervous or angry.. He's not even aware he's doing it. My only wish was that we'd have been able to implement the entirety of the "dance", but apparently 47 minutes wasn't very realistic from a game design stand point.
