#5, Johnny 5, Johnny Unusual... That's weird (bonus points if you have any idea what I'm talking about).
You Bet Your Life started out as a radio show in 1947, then began airing on NBC-TV in 1950, and continued until 1961. It was ostensibly a quiz show, but it was primarily intended to showcase Groucho Marx and his ad-libbing abilities. At least half of the show was dedicated to him interviewing and conversing with the contestants. In fact, the show was later renamed, The Groucho Show, but only lasted a year longer after that.
Two to three couples, usually selected from the audience and not necessarily related, would appear on stage with Groucho in succession, and after a lengthy interview, would answer questions from one of twenty categories. The couple that scored the most would go on to a Jackpot round with one bonus question.
The actual game part of the show went through many scoring formats. Up through 1953, players started with $20 and had to wager some or all of what they had with each of up to three questions, hence the title of the show. However, this was later done away with because too many people were betting all their money and losing, thus ending their time on the show. In the Jackpot round the bonus question was worth $1000, plus $500 for each episode the bonus question was missed. If you really care out the scoring, check out Wikipedia. There were about five different versions of the game.
There was, of course, also the famous Secret Word, which was always a common word, announced at the start of the show. If a contestant said it, a Groucho-duck would drop down and they'd win $100.
The main draw of the show was naturally Groucho Marx. The show also had many famous or later to become famous people on it, such as Ray Bradbury, Phillis Diller and Harland Sanders (aka The Colonel who founded KFC). Several attempts were made to revive the show after Marx quit, with little or no success. Later hosts included Buddy Hackett, Richard Dawson and Bill Cosby.
