Hanging upside down

Morgan's newest adventure was with a belt instead of a bungee cord.  He hooked the belt around the clothes bar in his closet and then somehow (don't ask me how) tied it around both of his feet and hung himself upside down.  Luckily the belt didn't actually break in half until he was back right side up and hanging from it with his hands.  He brought me the leather belt, broken cleanly in half and asked me if I would fix it so he could hang upside down again.
