Pangit

Dave goes round to Jim's house to visit him as he's just home from hospital after an operation. Jim is lying on the couch and after chatting for a while Jim asks Dave to pop upstairs to get his slippers. Upstairs, Dave sees Jim's two teenage daughters lying on their bed. So he tells them that Jim has sent him upstairs to fu*k them both.They both look at him incredulous and say they don't believe him. So he says, he'll prove it and shouts down to Jim - "Both of them Jim " and Jim replies "What's the use in fookin one"!
