I just watched the episode on which Rusty could not play in the basketball game because, even though he was making good grades in most of his subjects, he was not making good grades in history.

The boy who came to the Williams apartment with Rusty's homework was played by Kevin O'Neal. Mr. O'Neal was an actor who was the brother of Ryan O'Neal. He appeared as the grocery delivery man in the film What's Up, Doc?
