Harpo was a member of the American comedy team known as the Marx Brothers. The brothers enjoyed success in vaudeville, on Broadway, and in motion pictures from the early 1900s to about 1950. Harpo never spoke during their performances and instead blew a horn, whistled, or mimed to communicate. He also got laughs with his prop-laden sight gags, many of which involved the seemingly infinite number of odd items he managed to produce from his topcoat’s oversized pockets. How did he get his nickname? Discuss
