Murphy calls to see his mate Paddy who has a broken leg. Paddy says, "me feet are freezing; could you nip upstairs and get me slippers?" "No bother" says Murphy and runs upstairs. There are Paddy's two stunning 19yr old twin daughters sitting on their beds. "Hello girls, ya da sent me up here to shag ya both." says Murphy. "Feck off ya liar!" they say. "I'll prove it!" says Murphy. So he shouts down the stairs, "Both of em Pat?" "Of course, what's the use of fecking one!"
