Uncle Johnny

One day Adam's teacher told the class that everyone must find out a moral for the next day's class.
One boy came in and said, "Don't count your chickens before they hatch."
The second boy said, "Don't judge a book by it's cover."
Then Adam came in with a broken jaw and black eyes and said, "I asked my Uncle Johnny for a moral and he told me to shut up. I told him he had to help me because it was homework." The teacher said, "What is the moral, Johnny?"

"DON''T MESS WITH UNCLE JOHNNY WHEN HE'S DRINKING!!!''
