One of several {{Game Show}}s produced by Creator/{{Nickelodeon}} following the success of their original offering, ''[[Series/DoubleDare1986 Double Dare]]''. Teams competed in head-to-head stunts (known as "events") to earn money and eventually the right to enter the [[BonusRound Locker Room]] at the end of the show. The show was hosted by Michael Carrington in the first season, taped in Philadelphia[[note]]at the studios of the local Creator/{{PBS}} station WHYY-12, where ''Double Dare'' and the Eure era of ''Series/FindersKeepers'' also taped[[/note]], who was replaced by Skip Lackey when the show moved to Orlando and Universal Studios.

As the title suggests, unlike ''Double Dare'' and ''Finders Keepers'', ''Think Fast'' had less to do with physical activities and more to do with brain teasers and other memory challenges, like dumping colored slime on your teammate in a certain pattern a la Simon.

Each show consisted of four events (worth $50 for the first two, $100 for the other two), after which the winning team would win money and a chance to solve the "''Think Fast'' Brain Bender", usually a picture or a rebus covered by puzzle pieces. One would be uncovered after each event. Solving the Brain Bender was worth $200. The team with the most money won the game and advanced to the Locker Room.

!!GameShowTropes in use:
* BonusRound: In the Locker Room, the contestants had to match the contents of 15 large lockers, each of which contained either a silly character, a prop or series of props, or a "booby trap" of some sort (the Carrington episodes had props, puppets[[note]]specifically, a puppet of UsefulNotes/RonaldReagan giving a speech and flopping around[[/note]], and some people dressed as crazy characters while the Lackey episodes had people dressed as crazy characters and props). One at a time, a locker would open, and then the player had to find its match by hitting the buttons in front of the lockers to open them. Each successful match won money or a prize. All but one of the lockers contained something that matched with another locker's contents; the remaining locker contained a gimmick meant to throw off or hinder the players' progress:
** '''Carrington Era:''' The first contestant had 30 seconds to make as many matches as possible before the second went. The unpaired locker contained a "TimeBomb", which would "go off" after 20 seconds if not revealed. If the first contestant found the Time Bomb in time, the second got the full 30 seconds to make matches; however, if the Time Bomb went off, the second player only received 20 seconds (in very early episodes, finding the Time Bomb also ''added'' 10 seconds to the second player's time, for a total of 40 seconds; likely changed due to too many winners). Finding six of the seven pairs in time won the grand prize.
** '''Lackey Era:''' Players alternated making matches for 60 seconds. The odd locker contained the "RedHerring", an item or character with no match. The only way to proceed was to pull on a special "Herring Handle" at home base. $100 per match for the first four, two prizes of increasing value for five and six, finding all seven won the grand prize.
* ConsolationPrize
* CoveredInGunge: Many of the events, because it almost wouldn't be Nickelodeon without it.
* DoubleTheDollars: Round 1 events were worth $50, Round 2 events were worth $100.

** StudioAudience
* PromotionalConsideration
* RulesSpiel
* ShowTheFolksAtHome: The identity of the "Red Herring" in the Lackey era.
* SpeedRound: If both teams did not guess the Brain Bender after the 5th (and final) event, They go to the ''Speed Up Brain Bender'' before advancing to the locker room.

!!This version provides examples of:
* ColourCodedArmies: The Gold (yellow) Team vs. the Blue Team.
* ExcitedKidsShowHost: Lackey, in the "over sixes" variety. "[[NoIndoorVoice LOCK IT UP LOCK IT UP LOCK IT UP LOCK IT UP!!!!!]]"
* LuckBasedMission: Plumber's Blackjack, in which the contestants had to fill a container with randomly-sized beakers of water that corresponded to numbers on cards. The first team to go over lost.
* ProductPlacement: Converse All-Stars. [[ProductDisplacement Inverted]] in some of the games with grocery items, as at least parts of the brand names were usually covered with tape.
* RedHerring: Played straight in the Lackey-era Locker Room, as outlined above. Also, pulling the Herring Handle released a bunch of red plastic fish onto said character or item.
* SimonSaysMiniGame: A number of games were based on this, including punching in numbers on a large telephone, throwing four colors of paint-filled balloons at one's partner, or burping the "three gross uncles".
* SongsInTheKeyOfPanic: "Hurry" variant in the Locker Room; all variants of the music except for the Carrington version's standard 30-second cue doubled in tempo and added a drumroll with around 10 seconds left.
* TheTeaser: During the original era, Carrington would open each episode by saying "Hey you....think fast!" Sometimes, he'd use a prop from one of the day's events or locker contents to do so.
** During the first era of the Skip Lackey era, Locker room characters would chat as the announcer says "We are here inside the Think Fast Locker room where you can find the matching pairs but look out for the evil red herring today on...." And the locker room character would then shout "THINK FAST!"
** During the second era of the Skip Lackey era, The announcer would say "Today inside the Think Fast locker room, If you can find a matching pair then you got what you take to win cash and prizes $100. But somewhere inside alerts the ever smelling, Red Herring!"
* TimeBomb: Played straight in Carrington-era Locker Room, albeit with no actual destruction except to the second player's time limit.
* TimedMission: The Locker Room, both in finding the matches and the Time Bomb.
