These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: JoJo's Circus
Anvilicious: An episode in which the Spudinskis were depicted as literal couch potatoes and had become stuck to their couch due to lack of exercise.
Ear Worm: The theme song, certain others of the songs on the show as well - it featured at least one per episode.
Moe: JoJo herself, due mostly to her absolutely-adorable voice.
