American comedians. Groucho was the fast-talker; he had glasses, a cigar, and painted eyebrows and mustache. Harpo had curly blond hair and a top hat; he was always silent, except for his bicycle horn. He played the harp and was a complete loon. Chico had a bad Italian accent and played the piano. Zeppo was the straight man. Many of their films, like "Duck Soup", "Animal Crackers", and "A Night at the Opera", are still funny today.

vebelfetzer points out that Harpo had red hair which ended up looking blond on black-and-white film.
