Well some of my top, boven ones are definitely Bludgeoning Angel Dokuro-chan, Ouran HSHC, Baka and Test, Hetalia, and Lovely Complex; but I think the one for the top, boven spot probably has to be Mitsudomoe. I CANNOT put into word how hysterical this anime was XDD
Jubei-Chan: Secret of the Lovely Eyepatch. its been a while since i've watched it (i have it on VHS tape), but at the time i did, i don't think any anime made me laugh harder. there was probably something funnier that i watched much later, but i can't think of it right now.
