Serving Bears at Bars

A bear walks into a bar and asks the bartender for a beer. The bartender says, "Sorry, we don't give beer to bears in bars." The bear replies, "If you don't give me a beer, I'll eat that lady over there." The bartender says, "Go ahead." So the bear eats the lady and asks for a beer. The bartender says, "Sorry, we don't give beer to bears on drugs." "What do mean," asks the bear. "I'm not on drugs." "Yes, you are, that was the bar bitch you ate."

Worm Experiment

Four worms were placed into four separate jars. The first worm was put into a jar of alcohol. The second worm was put into a jar of cigarette smoke. The third worm was put into a jar of sperm. The fourth worm was put into a jar of soil. After one day:
First worm - dead Second worm - dead. Third worm - dead. Fourth worm - alive. Lesson: As long as you drink, smoke and have sex, you won't get worms!

Math Dealer

"Psst, c'mere," said the shifty-eyed man wearing a long black trenchcoat, as he beckoned me off the rainy street into a damp dark alley.
I followed. "What are you selling?" I asked.
"Geometrical algebra drugs."
"Huh!?"
"Geometry drugs. Ya got your uppers, your downers, your sidewaysers, your inside-outers..."
"Stop right there," I interrupted. "I've never heard of inside-outers."
"Oh, man, you'll love 'em. Makes you feel like M.C. ever-lovin' Escher on a particularly weird day."
"Go on..."
"OK, your inside-outers, your arbitrary bilinear mappers, and here, heh, here are the best ones," he said, pulling out a large clear bottle of orange pills.
"What are those, then?" I asked.
"Givens transformers. They'll rotate you about more planes than you even knew existed."
"Sounds gross. What about those bilinear mappers?"
"There's a whole variety of them. Here's one you'll love -- they call it 'One Over Z' on the street. Take one of these little bad boys and you'll be on speaking terms with the Point at Infinity."
