The first guys says, "I think my wife is having an affair with the mailman."

The other guys ask him why he thinks that and he replies, "We'll, the other day I found a mail bag under my bed."

Then one of the other guys says, "I think my wife is having an affair with the plumber....I found a wrench under my bed."

The last guy looks really troubled and says, "Guys, I think my wife is having an affair with a horse!"

The others say no way! Why do you think that?

"The other day I found a jockey under my bed!"
