The Doom Buggy

Don has dropped out of school to be a mechanic. But when he and Billy get lost in the desert, he sees that he doesn't know as much as he thought he did. Moral: If you close your mind to learning, sooner or later you're going to have it opened and be surprised at just how much you've shortchanged yourself. So if you ever think about dropping out of school, you're only hurting yourself.
