Well, since I see ‘Most Epic Scene Ever’ on this list, I guess I have to go a different route here. There is one scene that I can keep watching over and over and for some reason it never gets any less funny, and that is a scene from episode 13 of Fruits Basket.
Background on the show’s not entirely important here, barring a note I’ll get to in a minute, but the three main characters, Yuki, Tohru and Kyo meet up with Yuki and Kyo’s cousins, Hatsuharu and Momiji who recently started going to their school. Momiji looks really young for his age, and decided that he’d look cuter in a girl’s uniform than in a guy’s. The class president sees this and demands that he change into a boy’s uniform immediately to conform to school dress code.
Hatsuharu, hearing his loud and obnoxious blatherings, gets incredibly irritated, snaps and ‘goes black’. The note I was mentioning before was that Haru and the Sohma family, Momiji, Yuki and Kyo included, are cursed with different animals from the Chinese zodiac. Yuki’s the mouse, Kyo’s the cat (different story), Momiji’s the rabbit and Haru’s the ox. Because of this, Haru has a bit of a side effect where he has basically two sides of his personality; the white side which is extremely calm, kind and respectful and the black side which is really intense, angry, violent, flirtatious and sometimes rude. He doesn’t get many moments to show off this side, and this is definitely the best black Haru moment in the series.
He chews the living crap out of the Class President going on the best tangent ever trying to argue his side for Momiji. The Class President keeps trying to fight back, but gets shot down time and time again. Even when he gets put down a peg with a bit of logic, he calls out Haru for also not obeying the rules by assuming his hair is dyed because it’s both black and white. (It’s really that way because….well, moo)

I don’t really want to explain the scene full out, watch it for yourself, but it did include one of the most shocking and risque moments in the series at the end of the scene. It’s absolutely hilarious when you realize what he did.
Technically, Momiji was in the wrong here as you agree to school rules when you enroll, including dress code, but it was incredible to see this loud hothead get his ass verbally handed to him.
