A simple young man got very drunk one day and was caught short on the way home so he relieved himself in the local river. At that moment a policeman came along and shouted to him.
“Stop that immediately, put it away and go home, you drunken sod.”
The man stuck his d*ck back inside his trousers and started to laugh.
“What the hell are you laughing at?” demanded the policeman.
“Ha, ha,” replied the man. “I really tricked you this time. I put it away but I didn’t stop.”
