After two great seasons and two also great specials, there is always a possibility that a third season will ruin everything you liked, but here that's not the case, since as I said it actually becomes better.
In the 3rd season the delinquents are delinquents from the worst kind. In comparison to them the ones in the first season actually look like good and diligent students. (No, I'm not kidding!) What's more is that here the comedy reaches it's "highest point". This is definetly the funniest one from all the three seasons, and I don't mean just "funny", it's hilarious, even crazy. (I wan't just about to fall from the chair, I really actually fell down). You might think that after three seasons the jokes between Yankumi and Sawatari might wear out, but guess what? They are actually even funnier than before. I forgot to mention, but actually Namase Katsuhisa, deserves big applause for his Sawatari Gotou, not just in this season, but in all the others as well. As much as Yankumi is one in a million, he is the same. They will never be another character like this one (in all the good ways possible.)
What makes this season in particular, a little bit more special than the others to me, is that it actually introdused my honey, Miura Haruma to me. Even if this is the only one that stands on my favorite's list, in reallity I love all the three seasons pretty much the same. So as said before - Go, watch and educate yourself! ^^
