Several years ago I read about an English television special from Rowan Atkinson (Mr. Bean). It was his Guide to Visual Comedy.

He shows clips and acts out examples of what he is talking about.
As of this post update, here is an available video on YouTube of the complete program. Below are the parts I originally included.
