The show opens with a flashback to 1987: Henry, Shawn, and Gus are checking out at the supermarket. Shawn is trying to convince his dad not to make him put back one of his candy bars. Then he tries to get Gus to check out first, so he can con Gus into giving him his change so he can afford the extra candy bar after all. Henry and Gus call him out, though, and make Shawn go first. The cashier starts the transaction and a siren goes off. Shawn is the one-millionth customer, and he won prizes: a gift certificate and a cool bike. Shawn wants to know if he can use one of his gift certificates right now. The cashier tells him sure, and he buys ALL the candy bars at the checkout stand. Gus and Henry look on in disgust and disbelief.
