->''"Hi, My name is [guest], and I've got a secret!"''
-->-- Standard teaser opening leading into the credits.

GameShow from Creator/MarkGoodson-Bill Todman Productions, and basically a {{Retool}} of ''Series/WhatsMyLine''. Here, a person of some notoriety entered and gave his or her secret to the host, and the celebrity panel questioned them about it and tried to guess it. Each celeb had 15 seconds to question and/or guess the secret. Each stumped panelist earned the contestant money, and a full stump included bonus money. Celebrity guests with secrets were common.

The original show lasted from 1952-67. One-season revivals aired from 1972-73 and in 1976. Another revival aired from 2000 to 2003 on the Oxygen cable network, hosted by [[Radio/TheStephanieMillerShow Stephanie Miller]], and yet another version aired on Game Show Network in 2006.

* HomeGame: One was published by Lowell in 1956, and Don Ameche used it [[http://www.youtube.com/watch?v=Cwn5VV9FNdw to create a secret.]]
* Personnel:
** TheAnnouncer: Johnny Olson handled these duties on the syndicated and 1976 versions.

** StudioAudience
* ShowTheFolksAtHome: ...The contestant's secret.
----
!!This show provides examples of:
* {{Adorkable}}: Good ol' Bill Cullen (the "just so darn sweet" variety), especially in the earlier episodes.
* BroadcastLive: Garry Moore's run. Steve Allen lived on the West Coast and preferred to film a number of episodes at a time to reduce air travel.
* TheBusCameBack: After being fired following a lame segment involving Tony Curtis on June 11, 1958, series creator/producer Creator/AllanSherman returned in 1961 as a special guest riding on the success of novelty songs such as "Hello Muddah, Hello Fadduh."
* CampGay: The 2006 panel (Billy Bean, Frank [=DeCaro=], Jermaine Taylor, and Suzanne Westenhoefer). Jim J. Bullock was a regular on the Oxygen version.
* ChewToy: If the crew had something sneaky planned, the "victim" was most likely Henry Morgan. For example, he would be sent on an exotic trip (which started the moment the live broadcast ended) such as a safari in Africa, or working as a hired hand on Roy Rogers' Dude Ranch. Or carrying a spear in that night's production in the Metropolitan Opera. Or the fact that he was going to play Santa for some needy kids...or [[TopCat Arnold Stang's]] [[http://www.youtube.com/watch?v=DIZ0G5MrAfc secret on a Halloween episode that he used Henry's actual bedsheets for the ghost costume he's wearing.]]
* ChristmasEpisode: A regular tradition during the original series. One year, {{GSN}} used all 15 of a week's ''BlackAndWhiteOvernite'' slots to show them.
* CrossOver:
** Vivian Vance had the panel play a few rounds of "the exciting new CBS morning show" ''Series/{{Password}}''.
** One HalloweenEpisode found ''Series/BeatTheClock'' host Bud Collyer "trying out" upcoming new stunts for the next season on the panel. After the bit was over, Garry gave Bud a copy of ''Secret''[='s=] HomeGame while Bud gave him a copy of ''Clock''[='s=] HomeGame.
* ADayInTheLimelight: Panel regulars Bill Cullen, Henry Morgan, and Betsy Palmer each got a chance to guest host during Garry Moore's frequent boating vacations.
* DeadpanSnarker: Henry Morgan.
* EverythingsBetterWithMonkeys: Zippy the Chimp's secret was "I'm going to shine Henry Morgan's shoes". When he did so, he happened to flash the sole towards the camera, revealing a small hole. The next week, Garry Moore opened the show recounting the incident and talking about the great amount of mail that was sent to the show remarking about the hole, including some cobblers offering to fix it, some people sending in a few dollars so "poor" Henry could get some new shoes, and even a few pairs of shoes (both new and used).
* {{Expy}}: Of ''Series/WhatsMyLine''. When ''Secret'' creator Creator/AllanSherman brought the idea to Goodson-Todman, they initially rejected it as being a copy of ''Line''. Reportedly, Sherman replied that ''Line'' was so popular that '''somebody''' was going to copy it...so why not copy themselves?
* HalloweenEpisode: One just about every year, with secrets such as a man lighting a Jack-O-Lantern with an electric eel. The earlier seasons really got into the spirit of the holiday much heavier than later seasons, with one Winston episode in particular being downright creepy.
* LetXBeTheUnknown: The standard way of introducing a guest, such as [[http://www.youtube.com/watch?v=1qq_Mr1txFY Soupy]] [[Creator/SoupySales Sales]], whose name might be known to the panel. Lampshaded in one episode in which Garry Moore introduced three men as Mr. X, Mr. Y, and Mr. Z. Their secret? [[spoiler:Their real names were Mr. Ecks, Mr. Yie, and Mr. Zee.]]
* ObviousRulePatch:
** Early episodes had the panel question the contestant in two passes, each buzzer giving the contestant another $10. This was quickly changed to the "once around, $20 a buzzer" format.
** The time limit also became very loose during this period. They were notorious for buzzing the panelist just as they got the right answer.
** Originally, celebrity secrets were actual things about them or that had happened to them (i.e., Boris Karloff's "I'm afraid of mice"). This became both boring and limiting, and the gag/stunt secrets quickly evolved.
* OffTheRails: Several instances (such as a cow dropping "pies" live on the East Coast), but none moreso than George Burns forgetting his secret during the syndicated run.
* PieInTheFace: As part of his secret, Creator/SoupySales showed Garry how to get a laugh [[http://www.youtube.com/watch?v=1qq_Mr1txFY with a pie in the face.]]
* ProductPlacement: As was the usual custom at the time, the sponsor's logo would be seen on the front of the panel's desk, as well as on a small sign between Garry and the contestant. When Winston was the show's sponsor packs of their cigarettes would be given to the contestants along with the money, and whenever possible [[http://www.youtube.com/watch?v=6FfjEE2mSvM the distinctive Winston theme song]] would be worked into a secret such as being played on an "electric brain", or Jayne Meadows singing it in Chinese.
* RearrangeTheSong: The 1976 version's ThemeTune was later heard on ''Series/SecondChance'', and then in reorchestrated form on the Australian version of ''FamilyFeud'' in the 1980s.
* StageMoney
* {{Theremin}}: One Moore episode featured a theremin demonstration.
* ThoseTwoGuys: Bill Cullen and Henry Morgan. Being the two most consistent parts of ''Secret'' while hosts and female panel members changed around them, Bill and Henry seemed to share a genuine admiration and friendship for each other, and could often be seen leaning back talking to each other behind the seat of Jayne Meadows or Betsy Palmer between them.
* TransAtlanticEquivalent: Mentioned in an episode with a man whose secret was "I appeared on the Japanese version of ''I've Got A Secret''"; said Japanese version was called "''Please Guess My Secret''", had a panel made up of scholars and philosophers, and in Garry Moore's words unlike the UK versions of ''Secret''[='s=] sister shows "The Japanese just took the concept and made their own show" with no assistance from (or royalties paid to) Goodson-Todman.
* TreehouseOfFun: To help promote a change in day and timeslot, a female Flagpole Sitting Champion lived in a small treehouse built atop a pole in the middle of the stage from the last segment of the last Wednesday episode to the first segment of the following Monday's episode.
* TwentyMinutesIntoTheFuture: A number of secrets involved things that were still in the experimental stage during the Moore/Allen era, but commonplace now such as microwave ovens, Krazy Glue, and even a very primitive version [[http://www.youtube.com/watch?v=DJolOHBikQY of a computer audio file.]]
* WilliamTelling: On one [[BroadcastLive live]] episode, [[TheTonightShow Johnny Carson]]'s secret was that he would shoot an apple atop host Gary Moore's head. He did it too...with Moore safely behind a sheet of pexiglass.
