By this time, "The Four Marx Brothers" had begun to incorporate their unique style of comedy into their act and to develop their characters. Both Groucho's and Harpo's memoirs say that their now-famous on-stage personae were created by Al Shean. Groucho began to wear his trademark greasepaint mustache and to use a stooped walk. Harpo stopped speaking onstage and began to wear a red fright wig and carry a taxi-cab horn. Chico spoke with a fake Italian accent, developed off-stage to deal with neighborhood toughs, while Zeppo adopted the role of the romantic (and "peerlessly cheesy", according to James Agee) straight man.
