This morning I managed to catch "Happy Birthday to Me", an old horror movie starring one of the daughters from "Little House on the Prarie". If you ever get a chance, you should at least watch until you get to the big accident scene.
See, all during the movie, you know prarie-girl has been in a terrible accident and had a head injury needing some kind of brain surgery that involved putting a hinge in her skull for some reason, but you don't see the accident itself until a flashback about two thirds of the way through.
For reasons unknown, it's the most elaborate accident ever.
Prarie-girl and her mom are riding in a car, with Mom driving. But it's dark! And it's raining! And Mom's crying! And she's drunk! And a truck almost hits them! But it misses! And they end up on a bridge! But it's a drawbridge! And the opening is right under the car! And the car falls in the river! Mom opens the windows to let them swim to safety, but Mom is trapped by the steering wheel! And drowns! And prarie-girl swimps up and cracks her skull on the bottom of the boat that the bridge was raising for!
And that's how she injured her brain.
All it was missing was something on fire.
