Plot
Buster is busy playing a video game and his mom is about to leave and she tells him she wants the leaves raked. At first, she doesn't hear Buster and when Buster wins the level he's on he yells yes. It is 12:00 and by 4:15 Buster is still playing the game. Buster then sees it's 4:15 and realizes that he didn't rake the leaves yet and he looks outside to see large amounts of leaves all over the ground. Buster then calls Arthur to help him out and Arthur agrees to help him. When Arthur arrives, he is shocked to see the large amount of leaves, but he and Buster manage to rake all the leaves. The next day, Buster is paying marbles with his friends and he asked what they did yesterday and they all said they raked. Buster says that he had help from Arthur, which took half an hour to do and Francine asks him what is he going to do for Arthur. Buster says he doesn't know as Arthur didn't ask for anything even though he said he owes him. After his friends explains to him what interest is, Buster realizes he does owe Arthur and the next day Buster is busy raking Arthur's yard much to the surprise of Arthur who had already raked it. Buster tells him that he is returning all the favors he owes him and Arthur tells him he is more interested in the book he's reading and closes the door. Buster is at the park and Binky approaches him and asks what is he doing. Buster asks Binky has he ever owed anyone favors and Binky replies to him that he hasn't and Binky tells him that Arthur is an example of someone owes favors. Soon, Buster does Binky a favor by cleaning up his yard and his room along with turning in books to the library. Buster even saves Binky a spot in line for a movie. Then, Buster is doing favors for Francine, Muffy, then George, The Brain, and many others. Arthur and Buster go to a movie. Just as they get there Buster's phone rings and he leaves seconds after getting to the theater, much to Arthur's dismay. Arthur then catches up to Buster and asks what is going on and Buster reveals that he is paying back all the favors he owes him. As Buster's phone rings, Arthur falls into a small puddle and Arthur tells Buster he is not doing any more favors and says that he wants Buster to do his chores on time. They then shake hands with each other.
