Dave visits his doctor for advice on how to last longer when making love to his wife. 'Pleasuring yourself before sex often helps with this problem,' his GP explains. On the way home, Dave thinks about where he can act out his advice before going home to the wife. So he pulls his truck over in a quiet country lane, crawls underneath and pretends to examine it. Happy he has found privacy, he slides his trousers down and starts to pleasure himself. But just before the crucial moment, he hears a voice shout out: 'Police! What's going on down there?' 'I'm checking the axle' Dave gasps. 'Well you'd better check your brakes too,' the officer replies. 'Your truck rolled down the hill five minutes ago.'
