Tubular Cruise
On a rainy night, there was a crowd of people dancing on the deck of a ship. One by one, one person would leave the crowd of dancers and step up onto a pedestal near by. When they would leave, another person would join the dance and fill in. As the person on the pedestal stood there facing the dance, a large clear tube would slide down the wall and situate itself over the person; It was just large enough for their head to fit inside. The tube covered their head, then slid back up the wall taking the head with it. The now decapitated bodies would simply walk around the side of the boat and disappear.
