Favorite Unusable Rigs/Presets?

I love nasty or wierd tones, so when I say unusable, I simply mean things that just don't fit in your normal practice or live situations. Odd settings you stumbled on and such.

I've been using a modified version of "Ensemble Synth pault" to which I have renamed "Our Guitarist Is Outside." It literally sounds like that and I keep finding myself spending too much time playing on it.

Do you have anything different that you love to mess with?
