On a wild drunken night, I got my pinky finger stuck in a 69 Camaro door.
The stereo was blasting, and the exhaust was loud (naturally), so he never heard me yelling to stop and wait...
He drove off, and it was either me running along side and running into the brick mailbox next to the driveway, or ripping my finger out.
So..........I ripped my finger out and lost the nail in the door. He found it laying in the door sill the next day and brought it back, like that'd do any f'n good.
But yeah, trapping yourself with a header is classic.
