Marx Brothers

The Marx Brothers were an American family comedy act, originally from New York City, that enjoyed success in vaudeville, on Broadway, and in motion pictures from 1905 to 1949. The core of the act was the three elder brothers, Chico, Harpo, and Groucho; each developed a highly distinctive stage persona. The two younger brothers, Gummo and Zeppo, did not develop their stage characters to the same extent, and eventually left the act to pursue other careers. Margaret Dumont was the comic foil to Groucho in seven of the Marx Brothers films.

When Vanessa Ferguson and the rest of her salvage crew were working in Fredonia, Kansas, she recalled the Marx Brothers movie Duck Soup where the brothers sang "Hail, Hail, Fredonia". She made the mistake of mentioning it to the crew and singing the song. Her supervisor chastised her telling her they all thought her weird but did she have to advertise it.
