History Main / OnThree

* [[AvertedTrope Averted]] in ''Film/RobinHoodMenInTights'' with "On the count of 'Kick'!"
** Later it was "On the count of 'Jump'! Wait for it..."

* Shows up near the end of ''Film/SisterAct'', when [[TheFamilyForTheWholeFamily Vince's goons]] are getting ready to off Deloris:
-->'''Joey:''' Okay, we go one, two, three, shoot.
-->'''Willy:''' Wait. We don't go one, two, and shoot on three?
-->'''Joey:''' Get over there!

-->'''{{VideoGame/Sonic|TheHedgehog}}''': ''[to [[Franchise/TheLegendOfZelda Link]]]'' Okay, you're going to count to three. When you say "Two", you open the door!\\

* ''Series/TheGoodies'' discover this trope is not a good idea when you want to open a parachute. They hit the ground on three, whereupon the [[RuleOfFunny parachute belatedly opens]].

* The game ''TabletopGame/{{Uno}} Party'' features a card type called "Point Taken", represented by a pointing hand. Whoever plays a Point Taken card counts aloud from three. Then, on one, each player [[GivingSomeoneThePointerFinger points at an opponent]], and draw cards based on the number of people pointing at them, up to 5 cards.

* A running gag in ''Film/MontyPythonAndTheHolyGrail'' was that King Arthur couldn't say the word "three", substituting "five" for it until corrected by one of his subordinates. When it comes time to toss the HolyHandGrenade, he miscounts again-fortunately the grenade didn't go off until it was thrown next to the desired target.
** The instructions for the Holy Hand Grenade take this into an OverlyLongGag, making it even funnier when Arthur immediately flubs it:

* ''Series/BuffyTheVampireSlayer''.

* In ''Series/{{Life|2007}}'', Detectives Crews and Reese want to arrest a coke-dealer in an ice-cream truck (who has an armed partner hiding behind the counter):

* ''Series/AgentCarter''. Edwin Jarvis and Peggy Carter are cuffed to the desk in an interrogation room, so decide to use it to break the glass. Jarvis keeps interrupting to ask questions, but as per the RuleOfThree they succeed on the third try.
* ''Series/DarkMatter''

** Miguel and Tulio, hiding in barrels, plan to break out on three, but a heavy chest is placed on top before they reach three, trapping them in. They spend all night trying to get out, saying "Three! Thr-r-ree!" over and over. They eventually get out...in plain view of the crew.

-->'''Tulio''': On the count of three, pull back on the rope.
-->'''Miguel''': What? ''[They see one of the ships heading right toward them]'' [[OhCrap Agh!]]
-->'''Tulio''': Three!

--> First shalt thou take out the holy pin. Then shalt thou count to three, no more, no less. Three is the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, nor either count thou two, except that thou then proceed to three. Five is right out! Once the number three, being the third number, be reached, lobbest thou the Holy Hand Grenade toward thy foe, who, being naughty in My sight, shall snuff it.
