I thought this bit was the best:

Sit with your foot on the brake and load the engine to 3000 rpm, then release the brake and floor the throttle. Three things happen:

1. The front wheels leave the road.
2. The windscreen is suddenly full of sky.
3. 60 mph comes up in less than 2 seconds.

The missing number 4 is 'You cr*p yourself' but we figured that was too much information!
