Barry buys a new saxophone from auntie Wainright. Glenda doesn't let him play indoors, so he has to find a spot outside to practice. the problem starts when Barry discovers in what type of case the saxophone comes in. Compo and an old local man start a competition to see which one of them is in better shape. the challenges include, finding out who can climb a tree faster (problem is climbing down again), and who can go downhill faster, using Wesley's new invention. of course the winner is never found for various disastrous reasons
