The Credit Card
Eddie gets his own credit card and is bragging to Wally about it. Eddie has to charge a new car battery for Wally on his credit card. Wally pays him back in cash, but instead of putting the money aside, Eddie uses it to buy a new vest. When the bill comes from the credit card company, Eddie is in trouble because he doesn't have the money to pay them back.
