This is old, Oskar, but it was brought to mind by the paragraph in your "Paranoia..." post.
I had such a good laugh at that one, I remembered this one as equally funny. If anyone hasn't already seen it, I hope it gives them a chuckle.
The Ballad of Dumb George
"I cannot believe how incredibly stupid you are. I mean rock-hard stupid. Dehydrated-rock-hard stupid. Stupid so stupid that it goes way beyond the stupid we know into a whole different dimension of stupid. You are trans-stupid stupid. Meta-stupid. Stupid collapsed on itself so far that even the neutrons have collapsed. Stupid gotten so dense that no intellect can escape. Singularity stupid. Blazing hot mid-day sun on Mercury stupid. You emit more stupid in one second than our entire galaxy emits in a year. Quasar stupid."
