An Irishman was walking home late at night and sees a woman lurking in the shadows.
“Twenty Quid," she whispered.
Paddy had never had a hooker before but decides -- what the hell it's only twenty quid.
So they hide in the bushes. They're going at it for a couple of minutes when all of a sudden a light flashes on them. It's a police officer.
“What's going on here people?” asks the officer.
“Oi'm making love to me wife,” the Irishman answers sounding annoyed.
“Oh!! I'm so sorry,” says the cop, “I didn't realise.”
