"Monkey and the Cue Ball" joke

This guy walks into a bar with his monkey. The guy sits down next to the bartender and has a few drinks. After a while he has to go the bathroom.

"Will you watch my monkey while I go the bathroom?" the guy asked the bartender.

"Sure.", says the bartender.

As soon as the bartender hits the bathroom, the monkey jumps up, runs across the room to the pool tables and eats the cue-ball.

"What the hell?", the bartender exclaimed.

When the guy came out of the bathroom, the bartender says.

"Guess what?...your damn monkey just ate my cue-ball."

"Oh god.", says the guy. "Here there's $20 and after the monkey passes the cue-ball, I'll sterilize it and bring it back to you, deal?"

The bartender agrees. A week later the guy comes back with his monkey and also returns the cue-ball. He is now on good terms with the bartender. Anyway, the guy has a few drinks and after awhile he needs to go the bathroom. He looks at the bartender and says, "Will you watch my monkey while I go the bathroom?"

"He isn't going to eat the cue-ball is he?", asked the bartender.

"No he's over that.", explained the guy.

Bartender agrees. As soon as the guy hits the bathroom, the monkey jumps up, runs across the room, and gets a peanut out of the peanut bowl. The monkey examines the peanut. Then the monkey puts the peanut up it's ass, pulls the peanut out, and finally eats the peanut.

"What innnnnnn the hellllllll", the bartender exclaimed in a bewildered manner.

The guy comes out of the bathroom.

"Guess what?....your monkey just stuck a peanut up it's ass, and then ate it afterwards.", the bartender explained, still overcome by the act.

"Oh yeah...", the guy acknowledges. "It's just that ever since the cue-ball, he just wants to make sure everything fits."
