Above is a video with clips of both Charlie Chaplin and Buster Keaton boxing. The differences in their approach to the humor of the situation is obvious. Chaplin is a trickster, frequently outsmarting his opponent whereas Keaton is a complete stumblebum.
I've never been a big Chaplin fan, thinking many of his jokes are too cute for their own good. I much prefer Keaton's physical humor -- his getting tangled up in the ropes trying to enter the ring is good example of his work.
