Clown car
A clown car is a prop in a circus clown routine, which involves an implausibly large number of clowns emerging from a very small car. The first performance of this routine was in the Cole Bros. Circus during the 1950s. The effect is produced by simply removing all of a car's internal components — "including the door panels and the headliner" and "any interior barrier to the trunk" — and then filling the now-enlarged space with as many clowns as possible.
