Rowan Atkinson's great TV program Laughing Matters about physical comedy. As funny as it is instructive.
For some reason I can't embed the full show. The only thing I can embed is this clip above which is kind of part two of the below. But follow this link and you'll find a link to a playlist of almost the full show here.
Here are links to the individual parts: part one of five, two of five, three of five, Five of five
Part four seems to have slipped the cracks. I have chosen to post this even in the state it is, because its really worth a look. If you know of a better link I would love to know it.
