I've seen a fairly excellent spontaneous blog rap battle erupt amongst two of my friends, one of whom wished that he could've done it in French.

I'm sure that it's happened. If I weren't so tired and if I had less square pals online right now I would've done it already.

Fo' Shizzle, that'd be slammin'!

Been there, done that.

Won that

Done it.
