Charley

Charley is the commercially-available, programmable robot, Robonova, from Hitec (even though he's not actually a puppet). David Strassman brought out Charley, a small toy puppet (just for kicks) while the auditions were taking place. At first, Strassman pretended to shoot Charley and reacted in the expected way and other such cheap tricks. Chuck then instructed him to make Charley do this. His final instruction was to kill the audience. But Strassman scoffed at the idea when he had to get rid of Charley.
