In an effort to contribute to society and to make her boys useful at the same time, Lois "volunteers" Malcolm, Reese and Dewey for charity work at a local church. The boys are assigned to sort giant piles of donated clothing, game, appliances etc. Initially irritated at their new task, they realize the donated stuff is a lot nicer than their own possessions, and they begin swapping out their old stuff with the second-hand items. The boys soon make a enterprise out of their charity assistance, going as far as to sell things to the neighborhood kids - that is until Hal finds out. Meanwhile, Francis must come to grips with the fact his fabulous job in Alaska is not quite what he expected.
