Any episode of
SpongeBob SquarePants in which the character,
Squidward Tentacles, is unfairly injured/stripped of any dreams or hopes for that episode for the sole purpose of him being Squidward and being the "bad guy" when in reality, he's the character we
sympathize with. Also noted by an abnormally large IQ drop in SpongeBob or Patrick just for those episodes as well.
