Patouillard fait du Sandow.

Paul Berthos' doctor tells him he needs to get some exercise, and hands him some of those rubbery strings with handles. We had them around the house when I was a kid, sold by Jack Lalane and other exercise gurus. You could pull them apart, or attach them to a wall and get your whole body involved. As you might expect, Bertho attaches them to things that he should not.
