Background: 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.
Context: 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.

Background: English rock band Led Zeppelin's untitled fourth album, commonly known as Led Zeppelin IV, was released on 8 November 1971 by Atlantic Records. Produced by guitarist Jimmy Page, it was recorded between November 1970 and January 1971 at several locations, most prominently the Victorian house Headley Grange. After the band's previous album Led Zeppelin III received lukewarm reviews from critics, they decided their fourth album would officially be untitled. This, along with the inner sleeve's design featuring four symbols that represented each band member, led to the album being referred to variously as , Four Symbols, The Fourth Album, Untitled, Runes, The Hermit, and ZoSo (which was derived from Page's symbol).
Context: After the lukewarm, if not confused and sometimes dismissive, critical reaction Led Zeppelin III had received in late 1970, Page decided that the next Led Zeppelin album would not have a title, but would instead feature four hand-drawn symbols on the inner sleeve and record label, each one chosen by the band member it represents. "We decided that on the fourth album, we would deliberately play down the group name, and there wouldn't be any information whatsoever on the outer jacket," Page explained. "Names, titles and things like that do not mean a thing."  Page has also stated that the decision to release the album without any written information on the album sleeve was contrary to strong advice given to him by a press agent, who said that after a year's absence from both records and touring, the move would be akin to "professional suicide." In Page's words: "We just happened to have a lot of faith in what we were doing." In an interview he gave to The Times in 2010, he elaborated:  It wasn't easy. The record company were sort of insisting that the name go on it. There were eyes looking towards heaven if you like. It was hinted it was professional suicide to go out with an album with no title. The reality of it was that we'd had so many dour reviews to our albums along the way. At the time each came out it was difficult sometimes for the reviewers to come to terms with what was on there, without an immediate point of reference to the previous album. But the ethic of the band was very much summing up where we were collectively at that point in time. An untitled album struck me as the best answer to all the critics -- because we knew the way that the music was being received both by sales and attendance at concerts.  Releasing the album without an official title has made it difficult to consistently identify. While most commonly called Led Zeppelin IV, Atlantic Records catalogues have used the names Four Symbols and The Fourth Album. It has also been referred to as ZoSo (which Page's symbol appears to spell), Untitled and Runes. Page frequently refers to the album in interviews as "the fourth album" and "Led Zeppelin IV", and Plant thinks of it as "the fourth album, that's it". Not only does the album have no title, but there is no text anywhere on the front or back cover, or even a catalogue number on the spine (at least, on the original vinyl LP release).
