Unfaithful Wives

Paddy and his two friends are talking at a bar.
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"
