The monkey immediately runs up to a pool table and eats one of the cue balls. The man profusely apologizes to the bartender but the bartender said it was no big deal.
The following week, the man returns with his monkey but this time, the monkey’s up on the counter taking peanuts from the bowl, and sticking them up his (own) butt, then eating them. The bartender says “Look man, I don’t mind you bringing your monkey in here, he can eat all the cue balls and peanuts he wants. But he can’t be doing that! It’s gross, and he’s scaring the customers. The man replied. “Ever since he struggled to passed that cue ball, he’s been kind of sizing things up.”
