The Boy Who Knew Too Much

Bart fantasizes about riding on a raft with Huckleberry Finn. This is no accident, as the plot borrows heavily from Tom Sawyer. The night after he skips school, Tom and Huck sneak into a graveyard and witness a murder. The town accuses the drunk Muff Potter, but Tom is racked with guilt, knowing it was actually Injun Joe. Similarly, Bart skips school and witnesses the waiter's injury, later feeling guilty for not coming forward when Freddie Quimby is wrongfully accused.
