A man walks in a bar with his pet monkey. He sits down and orders a drink, meanwhile the monkey is running around all over the place and jumps up on a pool table. He grabs the 8 ball, shoves it into his mouth and swallows it hole.
“Holy crap!” says the bartender, completely livid. He says to the man, “Did you see what your stupid monkey just did?”
“Nope. What did he do this time?” says the man.
“He just swallowed one of the balls off the pool table, whole!” says the bartender.
“Yeah, well I hope it kills him ’cause he’s been driving me nuts” says the man.
After finishing his drink, the man leaves.
A few weeks later the man returns to the bar with his monkey. After ordering a drink, the monkey starts running wild around the bar again. Up on the bar, he monkey finds some peanuts. He grabs one out of the bowl, sticks it up his butt, then pulls it out and eats it. The bartender is disgusted.
“Did you see what your stupid monkey did this time?” he asks.
“What now?” responds the man.
“He stuck a peanut up his butt, then pulled it out and ate it!” says the bartender.
“Well, what do you expect?” replied the man. “Ever since he ate that pool ball he measures everything first!”
