Korean War). Each episode began with the introduction "And now, here he is: the one, the only..." by Fenneman, who would pause, inviting the audience to finish the sentence by shouting in unison "GROUCHO!" Groucho replies, "Oh, that's me!" and the show's band would then play a portion of the tune "Hooray for Captain Spaulding", Marx's signature song. Groucho next would be introduced to the first two contestants and engage in humorous conversations in which he would improvise his responses or employ prepared lines written by the show's writers using pre-show interviews. The total number of contestants in each episode varied depending on the length of Groucho's conversations and the time taken for gameplay in each segment. Generally, however, the 30-minute format of the televised show provided time for two or three two-person teams to play in each episode. Some show tension revolved around whether a contestant would say the "secret word", a common word revealed to the audience at the outset of each episode. If one of the contestants said the word, a toy duck resembling Groucho—with eyeglasses and a mustache—descended from the ceiling to bring a $100 prize, which would then be divided equally between that segment's two-person team. A cartoon of a duck with a cigar was also used in the opening title sequence. The duck was occasionally replaced with various other things, for example a wooden Indian figure, carrying the required $100 prize to the lucky team. In one episode, Groucho's brother Harpo came down instead of the duck, and in another a female model attired in a tight bodice and very short skirt came down in a birdcage with the money. In his conversations with contestants, Marx would at times direct their exchanges in ways to increase the likelihood that someone would use the secret word. In November 1955, Groucho announced on the air that he had noticed the success of big-money quiz programs (referring to, but not naming, The $64,000 Challenge) and declared that You Bet Your Life was itself going to raise its "Secret Word" bonus: from $100 to $101. This gimmick lasted until the end of the year. Formats Main game After the contestants' introduction and interview, the actual game began. Couples were allowed to choose from a list of 20 available categories before the show; then they tried to answer a series of questions within that category. From 1947 to 1956,
