Affair with a Horse

Paddy and his two friends, Bill and Simon, are talking at a bar.

Bill says: “I think my wife is having an affair with the electrician.”

“What makes you think that?” asks Paddy.

“Well the other day I came home and found wire cutters under our bed and they weren’t mine.”

Simon then says: “Same with me! I think my wife is having an affair with the plumber.”

“The other day I found a wrench under the bed and that wasn’t mine.”

“That’s all three of us then,” says Paddy: “I think my wife is having an affair with a horse.”

Bill and Simon look at him with utter disbelief.

“No, I’m serious. The other day I came home and found a jockey under our bed.”
