Revealing an old carnival scam called "pricking the garter"

In this episode of Scam School, Brian Brushwood reveals the secret behind a crooked carnival game called "pricking the garter." In the game, the sucker is asked to place his finger in one of two loops in a rolled up belt. After the belt is unrolled, if the sucker's finger is still inside the loop, he wins. But he never wins because the carny is always in control of the outcome.
