To be fair, you have to have a very high IQ to understand Ingoku Danchi. The humor is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also Yoshida's pure outlook, which is deftly woven into his characterisation - his personal philosophy draws heavily from Leo Tolstoy literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realize that they're not just funny- they say something deep about LIFE. As a consequence people who dislike Ingoku Danchi truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Doji Usa Porori's existencial catchphrase "Diiiiiiick!🎵", which itself is a cryptic reference to Christopher Moore's American epic Lamb I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Sakusei Kenkyuujo's genius unfolds itself on their screens. What fools... how I pity them. And yes by the way, I DO have an Ingoku Danchi tattoo. And no, you cannot see it. It's for the housewives eyes only- And even they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand.
is this the third male character who has face?
No, there was this guy too and Shouda (the tall housewife) husband too. I don't remember if there was anyone else. I'm considering only characters without glasses.
