(the whole thing tells a story: Truck backs up to dead car. Flat
plate slides back and back end touches ground to form a ramp.
The car is gonna go up that ramp, but how? Chain is hooked under
car somehow. Other side of chain is hooked into rotating thing.
Motor turns and makes appropriate groaning noises. car moves
closer and closer as chain gets wrapped around spool thing. Car
goes up ramp and gets closer and closer - will it hit the spool
thing? Motor shuts down with apropriate noises. *whew*. Truck is
safe. Car is safe. "
