Chaplin exploited that fact with The Tramp.
Funnier than the fool "is the man who, having had something funny happen to him, refuses to admit that anything out of the way has happened, and attempts to maintain his dignity," Chaplin once said.
"That is why, no matter how desperate the predicament is, I am always very much in earnest about clutching my cane, straightening my derby hat, and fixing my tie, even though I have just landed on my head."
