This is the anime equivalent of a guy who never breaks character, and it wears you down until you're laughing at things that aren't even jokes yet. Kariage-kun doesn't want money, revenge, or a girlfriend. He wants his department head to suffer, publicly, and he'll commandeer a park PA system to inform every stranger within earshot about the man's hemorrhoids to get there. He'll paper a whole district with notices for a fireworks display and then show up holding one sad little sparkler, and the punchline is that he's completely satisfied. It's yonkoma comedy played straight from Ueda Masashi's Weekly Manga Action strips, four panels of setup and detonation, no arcs, no growth, no lesson learned across 59 episodes. Watch three in a row and you'll start eyeing your own boss differently, which is exactly the problem.
Based on Ueda Masashi's four-panel manga from Weekly Manga Action, Kariage-kun is a comedy about the daily life of its title character, whose irony and sarcasm can land on anyone or anything. His usual victim is his department head, whom he humiliates by announcing over a park loudspeaker that the man has hemorrhoids. In another stunt, he posts a notice promising a fireworks display, then disappoints a whole district by showing up with a single small firework. The episodes have no particular beginning or ending, but they run in chronological order, tracking the changing seasons.
