"Wives Have Other Interests" joke

Paddy and his two friends are talking at work.

His first friend says, "I think my wife is having an affair with the electrician. The other day I came home and found wire cutters under our bed and they weren't mine."

His second friend says, "I think my wife is having an affair with the plumber. The other day I found a wrench under the bed and it wasn't mine."

Paddy says, "I think my wife is having an affair with a horse."

Both his friends look at him with utter disbelief.

"No, I'm serious. The other day I came home and found a jockey under our bed."
