Love Hina is the kind of light comedy you want when you have just been watching several episodes of a dark and battle-filled show. Love Hina is just so delightfully surrealistic and out there that you know it is not supposed to make sense, you should just enjoy it. With good characters and funny jokes, that is easy to do.
Poor Keitaro, always being sent flying for alleged pervitude! I have just watched episode 14, where the grey-haired Mitsune is trying to prevent Naru from seeing that her old tutor, who she used to have a crush on, is in town and working at the university. Naru is going to enter a room where the tutor is, and Mitsune hugs her from behind, then throws her in Keitaro's arms, saying he must hold on to her - or she will turn into a cow!
While Keitaro contemplates this with his usual surprised look, Kotomo comes around the corner, seeing him hug Naru. "Aha! Up to your old tricks again I see!" Then she sends him flying with her wooden sword. The scene is just so hilarious for some reason - you should be used to Keitaro's bad luck by now, but no, it's still funny.
