In Fast and Loose, a loop of chain is thrown into a figure eight by the operator. One side will hold fast when the chain is pulled, while the other will pull loose. The operator reads the player's body language and uses psychological ploys to force the player to pick incorrectly. In times past, it was a favorite con game for street swindlers and carnival men. As a busker, Dr. Wilson makes the old con game harmless by supplying the players with play money, which they swiftly lose in an amusing demonstration.
