Bartender: “You can’t bring that monkey in here!”
The man said: “Don’t worry, he won’t cause any trouble.”
Within seconds, the monkey jumped on the pool table and swallowed the ball.
The bartender said, “Hey, he just ate my balls
Nobody can play billiards now! Get out!”
The man left but came back a week later with his monkey
He apologizes to the bartender and promises that there won’t be any more trouble
The bartender left him and the monkey.
That night, the monkey went to a bowl of grapes and put one into the grape and ate it.
The bartender said, “This is disgusting! Why did he do that?!”
“He measures everything from the time he swallows the ball to before he eats it,” he said.
