Ruff realizes that he's a horrible shopper. (He just bought a sock at a yard sale for sixteen dollars, after talking the price UP from a quarter!) He also bought a broken tennis racquet at the same sale, which he plans on using in an upcoming match against his nemesis Spot Spotnick! Ruff sends Liza and Talia to the headquarters of Wilson Sporting Goods to design a new tennis racquet for him; and he gets some shopping tips from Bethany and Brian, as they head out to Brimfield Fair, the biggest flea market in the world!
