Jamie Oliver says preparation is all important in his 15-Minute Meals series. For example, keep your kettle on the boil so you're not wasting time waiting for hot water.
In the same way timing is important in a 15 minute punt. Need cock to spring to attention as soon as you're in the door, maybe start wanking as you approach?
Good idea for a new 15-Minute TV series after 9 pm.
