A gorilla goes into a pub and sits down on a stool at the bar.
The bartender, who was working a few feet away, was washing glasses when he saw the gorilla take his seat at the bar.
He was astonished to see a gorilla in the pub and ran back to the manager who was sitting in his office.
“Boss”, he said, “there’s a gorilla sitting at the bar. What do I do?”
“Well, we haven’t ever had a gorilla here, so give him whatever he orders”.
The bartender walked back and asked the gorilla what he would like.
The gorilla ordered a beer.
A moment later the bartender set a beer in front of the gorilla and the gorilla placed a $20 bill on the bar, which the excited bartender immediately picked up.
He ran back to his boss and said, “He just gave me a $20 bill. What should I do?”
“Well, I’m guessing gorillas don’t know too much about money, just give him 50 cents change”.
So, the bartender goes back out, plops 50 cents on the bar and says to the gorilla, “Say, I know this may sound strange, but we don’t get too many gorillas in here”.
“Well”, the gorilla replied, “it’s no darn wonder at $19.50 a beer”.
