@gemlog Wow! No, I didn't, that's interesting!
The character used to be insanely popular in the USSR (and ex-Soviet countries), we even have our own animated cartoon about him (there weren't many other cartoons, hence the popularity).
The characters in it look very differently from what the rest of the world is used to, something like this.
No, the video is a joke of course, they do not actually play System of a Down song in the original cartoon 😆
But they do look like this.
