Limb from Limb

Last night we were at my parents' house, sitting around the fire pit, and listening to Isaac tell stories. He was telling his version of a "scary" story about a dog named Spike. In the story, Isaac told about how, during a game of tug-of-war, Spike "broke his limb." When asked which limb he was referring to, Isaac patted his hip, and said, "You know... your limb."
