Murphy was walking home late at night and sees a woman in the dark shadows.

"Twenty Euros," she whispers.
Murphy had never been with a hooker before,
but decides what the hell, it's only twenty
Euros. So they hid in the bushes. They're going at it for a minute when all of a sudden a light flashes on them. It is a Police Officer.
"What's going on here, people?" asks the cop.
"I'm making love to me wife," Murphy answers
sounding annoyed.
"Oh, I'm sorry," says the cop, "I didn't know."
"Well, neidder did I, til ya shined that bloody
light in her face!"
