Little Nancy is in the garden filling in a hole when her neighbor peers over the fence. Interested in what the cheeky-faced youngster is doing, he politely asks, "What are you up to there, Nancy?"
"My goldfish died," replies Nancy tearfully, without looking up. "And I've just buried him."

The neighbor is concerned. "That's an awfully big hole for a goldfish, isn't it?" Nancy pats down the last heap of earth, then replies, "That's because he's inside your effing cat."
