After Bart steals a key from Principal Skinner's office and gets himself into hot water, Marge and Homer send him to a "behavior modification camp." Homer is forced to cancel his much-anticipated trip to Las Vegas in order to drive Bart to the camp, but on the way there, Homer decides it's a great time to bond with Bart. Blackboard: 'Teacher was not dumped--it was mutual'.

While cave exploring with his family, Homer causes the cave to crumble and finds himself stuck upside down in the ceiling. Marge and Bart search for help while Lisa passes the time by telling Homer a story, which turns into a chain of narrated tales.
