An Englishman, Irishman and a Scotsman are drowning their sorrows down the pub.

"I can't believe it." says the Englishman. "Me and the wife- we've been together 15 years and today I found out she's been having an affair with a builder."

"How do you know it was a builder?" the others ask.

"I found a box of tools under the bed."

"Join the club." says the Scotsman. "Today, I found out my wife's been having an affair with a milkman."

"How do you know it was a milkman?" the others ask.

"I found a crate of milk under the bed."

"You as well?" asks the Irishman. "I've just found out the wife was having an affair with a fokkin horse!"

The other two look at him incredulously. "How do you know it was a horse?"

"I found a jockey hiding under the bed."
