GameShow created by Jay Wolpert for Creator/MarkGoodson, which aired on Creator/{{CBS}} from 1976-77. Host Creator/AlexTrebek read a series of clues to his two contestants, who were in {{Sound Proof Booth}}s. When one player buzzed in to guess the subject, the other player's booth closed. An incorrect answer resulted in a "penalty clue" and free guess for the opposing player. A correct answer was worth $50 and allowed the player to Dare their opponent to guess the answer with the next clue for $100. If the dared player missed, the darer could "Double Dare" with one more clue for $200. A correct answer on a Dare awarded $50, while one on a Double Dare awarded $100.

The first player to score $500 played the BonusRound against "The Spoilers," usually three men (sometimes two men and a woman) with doctorates in different disciplines. The contestant was shown a subject and tried to stump the Spoilers by choosing four clues from a pool of eight, with the ability to pass up to four if s/he felt them too easy. Each time a Spoiler didn't guess the answer, the contestant received $100; if a Spoiler guessed the answer, s/he received $100 and sat out for the rest of the round. If at least one Spoiler remained stumped after the fourth clue, the contestant won $5,000.

Not to be confused with Creator/{{Nickelodeon}}'s ''[[Series/DoubleDare1986 Double Dare]]'', which is something quite different.
!!GameShowTropes in use:
* BonusRound: Try to stump three doctorates by selecting just the right four clues from a pool of eight for $5,000.
* GameShowWinningsCap: $25,000.
* LosingHorns: Type A. Recycled from ''Series/ThePriceIsRight'', minus the first two notes.
* Personnel:
** TheAnnouncer: Johnny Olson and Gene Wood shared this role.
** GameShowHost: Alex Trebek, in his only game for CBS.
** StudioAudience
* ShowTheFolksAtHome: Any time a new subject was put into play, Trebek would remind viewers to look away until they heard the bell if they were playing along at home.
* SoundProofBooth: Each contestant was placed in one, as were each of the Spoilers.
!!This series provides examples of:
* EpicFail: Even after the maximum 10 clues, both players were unable to identify Louise Lasser, the star of ''Mary Hartman, Mary Hartman''.
* FunnyAfro: Trebek, believe it or not. Complete with the PornStache he used to have, the man could not ''look'' more 1970s than he did on ''Double Dare''. And he had it during almost all of his 1970s hosting gigs.
* GettingCrapPastTheRadar: During the final few episodes, the writers were starting to have fun with their clues (well, if that worked for getting ''[[Series/MatchGame The Match Game]]'' UnCancelled...). The GrandFinale featured an infamous round with [[ some rather racy clues]] for "[[spoiler:boomerang]]". The hilarity is only amplified further through Trebek, who was either completely oblivious to what they planted in there, or outright knew and delivered it straight.

"In the film ''Walkabout'', the lead male straps one against his thigh with his loincloth."\\
"To use one properly, [[ADateWithRosiePalms grip it firmly with three fingers at the curve near the tip]]."
** This clue for [[ToiletHumor "Toilet"]]:
-->"When members of the French Resistance used this in World War II, they'd say, 'I'm off to telephone Hitler.'"
* RecycledSoundtrack: Probably as a payback for taking assorted sound effects from other CBS shows (including ''Series/ThePriceIsRight'''s LosingHorns and the ''Main/TriviaTrap''/Penny Ante noise), the theme music (as well as the entire structure of the intro itself) was later recycled on ''CardSharks''.
* SophisticatedAsHell: Trebek.
