 Bobby becomes self-conscious when he s the shortest one in the family, and becomes convinced he s going to remain height-challenged all his life. Following an ill-advised attempt by his sisters to encourage Bobby (they make him think he s grown 1 1/2 inches by doing stretch exercises) and then trying to flaunt his know-it-all genius, he has a chance to save Greg when they become locked in the meat freezer at Sam s Butcher Shop.
