A young mother is pregnant with triplets when she is shot by a gunman. A few years down the road, her firstborn, a girl, comes in and says "Mum I just had a wee and a bullet came out". The mother is shocked, and it is increased when her other daughter comes in and says "mum I was having a wee and a bullet came out". Then, the boy comes in looking pleased with himself. "Don't tell me" the mother says, "you had a wee and a bullet came out" "No", the boy says. "I was having a wank and I shot the dog"
