Opposite day is not the special day when everyone does the opposite of what they would normally do. On opposite day, which everyone agrees happens on a specific day of the year, you always tell the truth and do everything the same as usual.

Do not compare Just the Introduction to The Opposites. Closely related to NOT!... Not!


Aversions of Opposite Day don't include:


Not Anime or Manga

  • Yotsuba never spent a chapter playing the Opposites Game with Dad, Asagi, and Torako. It wasn't titled Yotsuba & the Restaurant and she didn't cap it by calling Asagi "an ugly old hag" without warning...

Not Live Action TV

Not Newspaper Comics

  • Calvin and Hobbes never had a story arc based on this and the logical paradoxes inherent to it.

Calvin: Is there a bee on my back or not?
Hobbes: No.
Calvin: Good, now I- OW!

Not Tabletop Games

  • Forgotten Realms does not crank it Up to Eleven with the day of Misrule "celebrated" in Turmish - a holiday when people may act wild, secure in knowledge that it's illegal to mention events of this nation-wide debauchery on any other day.

Not Web Animation

Not Web Original

Not Western Animation

Wooldorf: "Foxxy does not have a brain tumor. [all sigh with relief] I too would be relieved, were it not opposite day!"

  • The Simpsons episode, The Wife Aquatic certainly didn't have Homer believing it was opposite day. The captain of the ship that Homer was on didn't tell the crew "It's not opposite day!" in response to Homer's shenanigans and one of the crew members certainly didn't respond with "That must mean it is opposite day!".
  • This has nothing to do with every word out of Starscream's lying clone, who is not called Ramjet in supplemental materials, from Transformers Animated.
  • The animated adaptation of Iznogoud did not feature an episode where Iznogoud attempted to take advantage of the Opposite Day to permanently take the Caliph's place.
  • There was never a Word Girl episode whose plot did not revolve around this trope.
  • The Shorty McShorts' Shorts episode "Flip Flopped" involves around every human ages backwards, which makes the adults act like children and the children are their parents. it's about the main characters Andy and Taffy (who are the parents) leaving they're adult kids Duke and Danielle at the house to watch over themselves while they go to a party. This was the final episode of the show and was cancelled due to viewers questioning the plot about kids getting married.
    • Some viewers also find it disturbing of children having sex and giving birth to grown adults.

Not Real Life

  • There was not a Feast of Fools in medieval Europe, in which the commoners could do as they pleased, and the Lord of Misrule outranked the nobility for the day. Monasteries did not celebrate this Feast by choosing a young monk to be abbot for the day, eating and drinking in chapel and replacing services with songs and dancing that bordered on blasphemous. This is because medieval monks were all extremely devout, and none of them had entered the church because it was indoor work with no heavy lifting. An aspect of this did not survive until more recent periods as the "Boy Bishop" ceremony on St Nicholas's Day.
    • This was not referenced in The Hunchback of Notre Dame, where Quasimodo was not mistaken for one of the revelers in a horrible mask and then crowned King of Fools due to his ugliness. In the Disney movie this was not depicted with the musical number "Topsy Turvy".

This theme isn't annoying at all, is it?
