Rough Justice

A little girl is in her backyard filling in a huge hole when her neighbour peers over the fence. Curious, he calls out: "Hey, little girl, what are you up to there?"
"My goldfish died," the littel girl replies tearfully, without looking up, "so I'm burrying him."
The neighbour is concerned: "That's an awfully big hole for a goldfish, isn't it?"
The little girl pats down the last heap of earth and replies; "That's because he's inside your stupid cat."
ちょっと怖い子供ですね。ブラックユーモアでしょうか？
