Did You Hear About The Monkey That Ate The Cue Ball?

A man is sitting in a bar with his monkey. (Ahhh, this old story!) The monkey jumps onto the pool table and grabs the cue ball, and immediately sticks it in his mouth and eats it. No big deal.

A few nights later, the man and the monkey are back in the same bar, and the bartender offers the monkey a grape. The monkey takes the grape in his paw, and proceeds to stick it up his ass. He then takes it out of his ass and eats it.

The bartender is shocked and asks the man why his monkey would do that. The man replies, "Ever since the cue ball incident, he measures everything before he eats it."
