The Longest Yard is the seventh episode of Lizzie McGuire's second series.
Jo McGuire gets roped into attending the Super Sports Expo with her husband, so she makes Lizzie cancel her plans for the day to stay home and watch Matt (and Lanny.) This infuriates Lizzie, but she tries to be responsible and stops the boys from playing with her dad's prize possession, a football autographed by the legendary Walter Payton. But Matt and Lanny managed to deflate the football anyway. Lizzie and Matt know they're in BIG trouble if they can't get the ball fixed, so Lizzie calls Miranda and Gordo over to help her come up with a solution to the problem.
Soon Lizzie has an ever bigger problem. The two young boys have gone off by themselves to try and get the ball fixed. Mrs. McGuire calls to say they will be late arriving home, but she suspects something is wrong when she talks to Lizzie, so Sam asks a couple of his softball buddies to go by the house and check on things. Lizzie and Miranda go off to find Matt and Lanny while Gordo waits at the McGuire house. At first he is happy to be alone with the TV and the refrigerator full of food, but when Sam's friends Jeremy and David come by to check up on things, he has to try to convince them everything is OK. Lizzie and Miranda finally find the boys at the Collector's Corner trying to replace the football. By this time Lizzie is more relieved that Matt is alright rather than worried about the football. She trades in the deflated Walter Payton ball for one autographed by Dick Butkus and the group manages to sneak in just as the parents arrive back home. But of course Sam notice the difference in the footballs. Lizzie and Matt come clean and each try to take the blame themselves, but it turns out that the real Walter Payton ball was accidentally destroyed a few months before--by Jo!
