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: Shin Chan
Complete Monster: The rival Kendo Teacher in the Series Fauxnale. In the flanderized Gag Dub, it was implied that he kidnapped his students. However, he's no saint in the original version. He raised his bokken at a student that lost to Shin, and probably would have done worse had Kenta not stepped in.
Ear Worm: The dubs ending theme "Party Party Join Us Join Us, Party Party Join Us Join Us"
Germans Love David Hasselhoff: In Spain, especially in Catalonia, they LOVE Shin-chan in the same way Americans love The Simpsons (maybe more), to the point the author went there several times and befriended the official translator - who eventually appeared in the manga. Hell! It can be argued that it's more popular there than in freaking Japan itself! There was even a Japanese TV show that made a special episode to explain it. Meanwhile, no matter how many dubs, (Gag-like or otherwise) are made, it seems the series can't never catch in America.
In the anime, there was a story about the Noharas vacationing in Barcelona. Even though there were lots of quite outdated and slightly off stereotypes (a tour guide named Carmen, paella, toreros, south-american looking people and flamenco) they included some nods at the catalonian fans (such as Shin-chan saying the paella is "Molt bo" (Very good) or doing the "Ass Dance" saying "culet, culet" (What Shin-chan says in the catalan dub, roughly "booty, booty")
The phenomenon isn't as widespread in Portugal, but here you can't be an anime fanatic without at least recognizing Shin Chan
I had no idea Shin-chan was Japanese until I saw a commercial on [adult swim] (they called him "Jangoo" in Korea(n)). I'm not quite sure about the extent of his popularity, but the show was popular enough in Korea to have the movies dubbed and a line of Shin-chan snacks sold in stores.
And Indonesia, alongside Doraemon and Dragon Ball, you are really lucky if you found any old manga on Indonesian bookstore, and they notably still has their anime running in Indonesia, and theres still a running new manga series in Indonesia for Shin Chan. Hell, not seeing a Doraemon or a Shin Chan manga in any place that sells manga is a massive acomplishment.
Ho Yay: With Shin and Kazama-kun (Georgie), a lot! Played for laughs, of course.
Shin-chan kinda teases Georgie a little too much.
The Scrappy: Misae/Mitzy gets this for being abusivetendencies. Sure, Shin is no boy scout, but she reacts to everything he does with the maturity of a 12-year-old.
