Three men are sitting at a bar and each admits that he thinks his wife is cheating on him.
“I found a hammer and a tool belt under my bed yesterday,” the first man says.”I think my wife is sleeping with a carpenter.”
“Well, I found a medical bag under my bed yesterday,” the second man admits.”I think my wife is sleeping with a doctor.”
“That’s nothing,” the third man says.”When I came home yesterday, I found a cowboy under my bed.I think my wife is screwing a horse.”
