<human>: You Bet Your Life is an American comedy quiz series that aired on both radio and television. The original and best-known version was hosted by Groucho Marx of the Marx Brothers, with announcer and assistant George Fenneman. The show debuted on ABC Radio on October 27, 1947, then moved to CBS Radio debuting October 5, 1949, before making the transition to NBC-TV and NBC Radio on October 4, 1950. Because of its simple format, it was possible to broadcast the show simultaneously on radio and television.

Contestant teams usually consisted of one male and one female, most selected from the studio audience. Occasionally, famous or otherwise interesting figures were invited to play (e.g., a Korean-American contestant who was a veteran and had been a prisoner of war during the Korean War).  Each episode began with the introduction "And now, here he is: the one, the only..." by Fenneman, who would pause, evoking the audience to finish the sentence by shouting in unison "GROUCHO!" 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.
