The Bouncer
The bouncer was a hairy guy named Harry. He had no teeth. He told everyone it happens when you start using too much torque. Your body stops getting calcium. Then you stop and let your body work again. By the time it's over, you've got a few bones broken and you miss your teeth.
He looked like fifty and no one believed him. They thought he was a junkie, but all he ever did was use too much torque. Perhaps it was because they came from outside the door.
