April Fool's Plot

Ah... April 1. It is the day where everyone can pull tricks at someone without worry. It is the time of the year where you let yourself loose and have light-hearted fun.

Television shows, of course, have plots based on April Fool's Day, much like the Christmas Episode. And much like holiday-themed episodes, they follow a recurring theme. Because Jerk Asses exists, they use this celebration to be a douchebag to everyone around them and simply yell "April Fools!" to be immediately immune from any form of criticism. They use the freedom of the day to be abusive towards others by pulling pranks and get away with it scot free!

Usually, the episode ends with the jerk getting his comeuppance ending with "April Fools!" being uttered by the former victim as he or she pulls a prank on the prankster. Of course, there have been variations, with even the prankster getting away with it.

Note that this is NOT about episodes that simply aired during April Fool's Day to commemorate it. This is simply about episodes with the story that focuses on April Fools Day, hence this trope's name. While it is possible for them to air during early April, that is not a requirement. If you are looking for episodes that commemorate April Fool's Day, simply go to April Fools' Day.

See Christmas Episode for another holiday-themed episode, or Very Special Episode for another specially themed episode.
