Buster decides to try his own hand at gardening in the community garden after using out home-grown compost on tomatoes and finding out that commercial ones do not taste as good. He also becomes friends with the garden's caretaker, Fritz Langley. Fed up with getting punished for incidents Timmy causes, Tommy asks D.W. to teach him good manners to prepare for Parent-Visiting Day and get a chance to win the Good Behavior Award. D.W. is hesitant at first, but when Emily proposes a bet, D.W. gives in and teaches Tommy good manners.
