Several slug trainers bring on their trained slug and deposit it in the stage center. A slug is a person encased in a sleeping bag. On command the slug performs various tricks such as rolling over, leaping in the air slightly, etc. A volunteer is brought from the audience and is told that the slug is trained to crawl over the human body. The volunteer lays down and the slug crawls across him leaving a dribble of water or brown cotton balls. The trainers apologize and exclaim, "Sorry, but our slug isn't potty trained."
