A very drunk Paddy met a prostitute up a dark alley.
He asks, “How much for full s*x?”
“£50,” she replies.
“Ok,” says Paddy, and they get down to business. Next minute, a Garda appears and shines his torch in their faces.
“What’s going on here, then?” he asks.
“Nothing, Garda, I’m just having s*x with my wife.”
“Sorry, sir,” says the Garda. “I didn’t know it was your wife.”
Paddy shouts, “Neither did I, till you shone your feckin’ torch in her face!”
