Charlie Chaplin is truly something very special. Anyone who can have a mustache so similar to Adolf Hitler yet still get away with it is a special person indeed. Most of the comedians you know today are just using movs they learned from Charlie Chaplin, or from someone who was using moves they learned from Charlie Chaplin. He was a king of comedy in the early part of the 1900s, but he wouldn't do well in 2018... because he's dead.
Charlie Chaplin was a master of movies with sound and a master of silent films. His specialty was physical comedy, so no doubt he needed his feet to make the bits work. He put out a nice insure policy so that if he laughter ever stopped, he'd still be OK.
