This false arm size is realistic enough to make a good joke to anyone! Let it hang stuck in the door of your closet, in the piano, in the trunk of your car, refrigerator, garbage, toilets, mailbox, under the wheel of your car, a window, in a drawer, in a bag, in the shower, under a piece of furniture, in a suitcase, in the bed of your sister .... well wherever you can scare your victim.

     * Exists only in the left arm (but still very scared)
