So this guy's walking through a medow and he sees this small girl, sitting down by a tree with her dog. He goes over to her and says: "Hello, little girl! What's your name?". She says, "My name is Petal!" He says that Petal is a lovely name and he asks how she got her name. "Well, when my mummy was pregnant, she was sitting here and a petal from that flower patch over there blew over and landed on her tummy, so she decided to call me Petal." "That's a beautiful story" he said, "and your dog is very cute! What's his name?" "Porkie" she answered. "And why is he called Porkie?" he asked. "Because he fucks pigs."
