Jumping Jack

Simeon Shamon says: "Mr. Jumping Jack is wasting his time!"[1]

A jumping jack is a type of toy. The jointed jumping-jack figure is a cross between a puppet and a paper doll. The figures are generally made from wood and their limbs are jointed and tied to a pull string. When the string is pulled and released, the arms and legs move up and down. An exercising move is also referred to as a jumping jack, from which it got its' name from the toy.

Batman tried to pound his feet on the steel trapdoors that led to Shamon's laboratory. Shamon could hear the pounding from below, and he said: "Mr. Jumping Jack is wasting his time!"[2]
