Murphy calls to see his mate Paddy who has a broken leg. Paddy says, "Me feet‘r fooking freezing mate, could you nip upstairs and get me fooking slippers?” "No bother at all" Murphy says and runs upstairs.
Murphy spies Paddy’s two stunning 19 year old twin daughters sitting on a bed.
"Hello girls, your Daddy sent me up here to shag ye both."
"Fook off ya liar" they say.
"I'll prove it" says Murphy. So he shouts down the stairs, "Both of them Pat?"
"Of course says Paddy, what’s the use of fooking one!"
