''In professional wrestling, anything that happened more than three months ago is [[CanonDiscontinuity no longer true canon.]]''

ProfessionalWrestling's version of NegativeContinuity and {{Retcon}}.

The unwritten rule states that any events that took place more than three months ago do not need to be considered {{Canon}}. This creates interesting situations where two wrestlers who were recently at each other's throats are now the best of friends. It also provides a means for the writers to not have to explain radical changes in a character's gimmick (went from a millionaire playboy to a voodoo priest and back again? No problem!).

Note that this is different from the [[FleetingDemographicRule Seven Year Rule]]; after three months, the aftereffects of a storyline can be forgotten, but after seven years, the storyline itself can be recycled wholesale.

[[folder: Professional Wrestling ]]

* An early storyline involving Wrestling/{{Kane}} established him as being a deeply disturbed, physically scarred, mute, masked monster. Throughout the years, Kane evolved from being mute, to requiring an electrolarynx to speak, to being able to speak normally. When he was eventually unmasked, his face was completely unscarred. Surprise!
** And in Kane's 2010 feud with Wrestling/TheUndertaker, he claimed that ''Undertaker'' removed his mask. They then showed footage of the time Undertaker did remove Kane's mask (but he put it back on the next day, it was two years before his actual unmasking). WWE probably wants people to forget about the SpecialEffectsFailure of Kane's real unmasking.
* Wrestling/{{Christian}} and Wrestling/{{Edge}} were initially referred to as being on-screen {{Kayfabe}} brothers when they were together as a tag team. When they semi-reunited a few years after their breakup, they were only said to be best friends.
* Eddie Fatu started in Wrestling/{{WWE}} as a street thug named Jamal, and was a few years later revamped as Wrestling/{{Umaga}}, a WildSamoan. It apparently runs in the family, as Solofa Fatu started out as a WildSamoan (as half of The Headshrinkers), then became a reformed gang member trying to "make a difference", and eventually became Wrestling/{{Rikishi}}, the hip-hop dancing, thong-clad sumo wrestler.
* This rule did lead to a [[SugarWiki/FunnyMoments Crowning Moment of Funny]] when Wrestling/TripleH (then a good guy) got [[http://www.youtube.com/watch?v=oZ4D1KhzbfU confronted by all the crap that he pulled on his team-mates when he was a bad guy]].
-->'''Wrestling/TripleH''': ''"... my bad, sorry."''
* John Hennigan was one of the contestants on ''[[Wrestling/WWEToughEnough WWE Tough Enough 3]]'', and ended up winning the competition and a WWE contract. He made a couple of appearances on ''Monday Night Raw'' under his real name before adopting a series of stage names, eventually settling on Johnny Nitro. Fast forward to July 2007, when Nitro announced that he was dropping the "Johnny Nitro" name and would now go by his given name -- ''Wrestling/JohnMorrison''.
** ...which was later changed, around the time he [[HeelFaceTurn turned babyface]], to be a deliberate {{homage}} to [[Music/TheDoors Jim Morrison]].
* Also, the three months does have some leeway if there's a contract dispute, a severe injury, or a star has scheduled major surgery. In these cases, storylines simply disappear and aren't even mentioned during shows. Nowadays, the promotion will usually put up a press release on their website explaining what happened, but the in-show announcers will completely ignore it.
** An injury or surgery can also often completely change how the crowd is to react to the wrestler in question. A main-eventer can be the dirtiest most unlikable cheater in the entire federation, get injured and be out for a while then come back as the biggest babyface around.
*** Inverted with Wrestling/RandyOrton, who became a heel through his infamous "Randy News Network" promos during his injury downtime.
* One of the major positives of small independent Wrestling/RingOfHonor is that it does ''not'' use this rule. A lot of fans were pleased when Kevin Steen & Wrestling/ElGenerico continued to despise the Briscoe Brothers a year after their rivalry, even though both teams were now {{Face}}s.
** ROH is not exempt though. Just one year after an extended, gruesomely violent feud that included a few cases of attempted murder (one incident including the use of Drano gel), Homicide and Wrestling/ColtCabana became tag team partners to take on the partnership of Adam Pearce and Brent Albright.
* [[Wrestling/TheDudleyBoys Spike Dudley]] gets a random WWE title "shot" (obvious he was going to lose; the main event with current holder Wrestling/KurtAngle was already being publicized). This causes the other Dudleys to turn on him out of jealousy as they had never been given a title shot, a pretty mediocre reason to break up a group, especially since Bubba had been given an equally-random title shot just months earlier.
* When [[Wrestling/VinceMcMahon Vince [=McMahon=]]] revealed himself as [[Wrestling/MinistryOfDarkness Higher Power]], his wife Linda and daughter [[Wrestling/StephanieMcMahon Stephanie]] gave their share of power in the company to Wrestling/StoneColdSteveAustin in revenge (the Higher Power had organized Stephanie's kidnapping by Wrestling/TheUndertaker.) At the 1999 ''King of the Ring'', Austin lost his power in a ladder match against Vince and [[Wrestling/ShaneMcMahon Shane [=McMahon=]]] who then held all the power over the company. Months later, Vince and Shane underwent a face turn and were feuding with Wrestling/TripleH. Stephanie then turned on Vince and married Wrestling/TripleH, forcing Vince and Shane into exile. Wrestling/TripleH then took over the WWF, citing Stephanie's share of the stocks in the company... which she technically didn't have anymore.
** In 2001, Stephanie bought Wrestling/{{ECW}} by selling the stock that she no longer owned.
* Kane's 2010 rivalry with Wrestling/TheUndertaker, which ended with Undertaker being buried alive (itself a good example of the FleetingDemographicRule) was brushed under the rug and forgotten when Undertaker returned around four months later. ''Maybe'' he was going to try and avenge himself, but before Undertaker could say anything Wrestling/TripleH waltzed in from out of nowhere and challenged him at Wrestlemania, so the whole storyline was forgotten. Though Undertaker's new theme song [[Music/JohnnyCash "Ain't No Grave"]] seemed to refer to it.
** Not to mention that WWE went entirely out of its way not to acknowledge that Undertaker had already fought TripleH at Wrestlemania before (at Wrestlemania 17). In fact they made it seem like Undertaker and Wrestling/TripleH had never wrestled each other at all period.
* Wrestling/KofiKingston originally debuted with a Jamaican gimmick, speaking with an accent, but eventually dropped the accent and started wearing hairstyles similar in tribal African communities. He was even being called from his hometown - Ghana, West Africa. This wasn't acknowledged until his partners in a team-against-team feud started to argue. He tried to calm them down in an American accent. Triple H interrupts him and asks, "Aren't you supposed to be Jamaican? What happened to your accent?"
* Wrestling/TrishStratus [[FaceHeelTurn turned heel]] on Wrestling/ChrisJericho at ''Wrestling/{{WrestleMania}} XX'' on March 14, 2004. Exactly THREE MONTHS LATER, on June 14, it was announced on ''Raw'' that Wrestling/{{Lita}} was [[{{Kayfabe}} "pregnant"]].[[note]]Wrestling/{{Kane}} had pulled a ScarpiaUltimatum.[[/note]] It was almost as if WWE had been waiting for the right moment to transfer the heat from Trish to the traditionally virtuous {{Face}} Lita. While not acknowledging how much time had passed since her turn, Trish pretty much nailed the irony of the situation.
-->'''TRISH''': "Imagine, and they call ME a slut."
** Oddly enough Trish's betrayal of Jericho ''was'' brought up as a ContinuityNod when she guest hosted Raw. Only this time Trish was the face and Jericho the heel, still enforcing the trope somewhat.
* Completely averted by Wrestling/{{CHIKARA}}, since they have a strong emphasis on continuity to the point that events from ''years'' earlier still play a part in whatever is happening at a given time. As an example, the debut of the BDK at the end of the 2009 SeasonFinale ''Three-Fisted Tales'', November 22, 2009, had roots going back to, ''at least'' 2007 and was connected to so many different storylines that time doesn't permit the listing of all of them here.

[[folder: Live Action TV ]]

* ''[[Series/{{Degrassi}} Degrassi: The Next Generation]]'' flip flops on this at times. Large WhamEpisode events carry over to later seasons easier than minor interactions. The largest event to get glossed over was Craig and Manny's aborted pregnancy. However the most obvious are friendships that reappear without any word when the two had a very vocal break-up (platonic or otherwise). The more recent seasons haven't been as bad about this. There are still moments (Clare and Jenna in ''All Falls Down'', is a minor recent example).
* Similarly, ''Series/BoyMeetsWorld'' had the unofficial rule of "If it was more than a season ago (or prior to the most recent {{Retool}}), it didn't happen". Pretty much the entire first season was ignored except in a one-shot CallBack in the fifth season finale, and several storylines in later seasons were [[RecycledScript ripped off]] from earlier ones. ''Two'' major Season 5 arcs (Cory and Topanga break up, Shawn gets his first serious girlfriend) had already been done in Season 3, but were treated as if they were unprecedented.

[[folder: Tabletop RPG ]]

* In the Veluna region of ''[[TabletopGame/{{Greyhawk}} Living Greyhawk]]'' there was a well-loved NPC named The Traveler who frequently (twice a year) needed rescuing from the [=PCs=] due to the dangerous places she traveled to. In Year Four of the campaign, it was ret-conned to claim that she had been evil all along. Her class, level, and spell selection changed; as did her personality. Only the name remained the same, although the WordOfGod insisted that it was the same NPC.
