Chaplin was the master of simple banana peel pane of glass in the kid. whereas Buster Keaton was more complex. you see Keaton use a lot more props the piano. the house itself,the porch railing he uses as a ladder. Also Chaplin was all about rising up against society. whereas Keaton everything seem to happen to him The piano falls on him then he fights it trying to get it in the house and when he does the floor caves in he is the man who can,t catch a break.
