David knocks over the pins
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
David initally planned for Paul to tow the caravan towards the pins, but once Paul got the car, David instead got Paul to bring the pins to him. Afterwards, Paul taught him how to drive and park the car. He knocked over all of the pins in 7 minutes and 28 seconds, receiving 4 points.
