 is a touchstone scene for Marx Brothers fans, as evidenced by Richard Anobile's book of the same name (featuring a foreword by Groucho) which focuses on the minutiae of the Marx Brothers' routines.The duck is a recurring reference throughout the Marxes' and especially Groucho's career.His signature walk was called "the duck walk" and on Groucho's television program "You Bet Your Life" a stuffed duck made up to resemble Groucho would drop from the ceiling to give contestants money if they said the day's secret word.
