Little Tim was in the garden filling in a hole when his neighbor peered
over the fence. Interested in what the cheeky-faced youngster was up
to,  he politely asked, "What are you up to there, Tim?" "My goldfish
died," replied Tim tearfully, without looking up, "and I've just buried
him." The neighbor was concerned. "That's an awfully big hole for a
goldfish, isn't it?" Tim patted down the last heap of earth then
replied, "That's because he's inside your stupid cat."
