How Do You Know If She Is Cheating?

Three men sat around a table in a bar and talked about their wives. The first man says, "I think my wife is having an affair with an electrician. When I got home last night I found a pair of pliers and some insulating tape behind the radiator in the bedroom - we've not had any work done on the house, and I can't think of any other way they could have got there". The second man says, "I think my wife is having an affair with a carpenter. Last night I found a toolbelt in the laundry basket, and we've not had any renovations to the house for years..." The third man says, "I'm in the same boat, but I don't think you two have it as bad. My wife is having an affair with a horse!" The two other man both look at him with confused look and demand an explanation. "When I got home last night I found a jockey hidden in the wardrobe."
