ooh oh i know!!!!! first i would paint the inside.
then, i would play doll house in it.
then, i would fill it with water and wash my clothes.
then, i would trap tiny bugs in it.
then, i would let moldy stuff grow on the inside, and throw it in my sister's room.
then, my sis would probably throw it back, so then i would wrap it in pretty paper.
then i would leave it on someone's front door and there will be a card that says "from your secret admirer".
oh if they gave back the fridge then i would probably scrape all the mold off and turn it into a rocket and actually light it on fire and then watch it slowly explode.
