Author William Peter Blatty once won $10,000 on this show. When Groucho Marx asked what he planned to do with the money, he said he planned to take some time off to "work on a novel". The result was the novel, The Exorcist (1973), published in 1971.
Reportedly, the reason why this show was prerecorded for broadcast was because the network was afraid that Groucho Marx's ad-libs would run afoul of the censors. In reality, another reason was to condense the interviews to fit the allotted time with the most entertaining material Groucho was able to generate with them.
Groucho Marx stated that the biggest laugh he ever got on the show was when he was talking to a female contestant. He asked about her husband, and she replied earthily, "Have you ever been made love to by a Frenchman?" The audience went into gales of laughter, and Groucho answered, "Not that I can recall!"
Although the ratings were still solid, the show stopped production because the producers wanted to begin syndicating reruns of the series. At the time, it was unusual to syndicate reruns of a series that was still on the air. So they replaced it with Tell It to Groucho (1962).
It is part of Hollywood legend that one of the source recordings for the "laugh track" sounds heard on sitcoms since the 1960s originated from a particularly long bit of laughter that erupted during an episode of this series.
One of the first TV variety shows to be pre-recorded. Eight 35mm cameras were used, duplicated in pairs, in four locations. While one set af cameras shot the program with 10-minute reels, the other set were re-loaded and put into action as the reels ran out.
Groucho Marx wore a toupee through out the series, except at the end of each episode when he told viewers to visit a DeSoto-Plymouth dealer and "tell them Groucho sent you" (filmed separately); he was seen without the toupee.
Although the popular impression is that Groucho Marx entirely improvised his jokes, in reality the show also had gag writers who interviewed the contestants beforehand and prepared questions and comments for Groucho to use in addition to his own improvisations. To feed them to him subtly, a Tele-Score bowling alley projector located stage left and out of camera range was used.
In every show a music theme is heard as the contestant spins a wheel. This music slows down like a record player which suddenly loses power. This bit of music was actually composed for the motion picture A Night to Remember (1942) when Brian Aherne's character pulls a burnt roast from an oven. The composer of the piece is Werner R. Heymann.
