In professional wrestling, anything that happened more than three months ago is no longer true canon.
's version of Negative Continuity
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 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.
- Degrassi: The Next Generation flip flops on this at times. Large Wham Episode 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, Boy Meets World 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 Call Back in the fifth season finale, and several storylines in later seasons were 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.
- In the Veluna region of 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 Word of God insisted that it was the same NPC.
