Peggy will buy anything at a yard sale, so when she brings home a boar's head, there's no more room in the garage to put it. So, Al decides enough is enough and he decides to have his own yard sale, despite Peggy's protests. But the stuff he is selling is stuff only Peggy would be stupid enough to buy. Al's next idea is to create "Bundyland, the happiest place on Earth," which is a collection of all the junk items Peggy bought in their own back yard.
