Anyone who likes humorous anime owes it to themselves to check this one out. It's one of the funniest animes I've ever seen, and certainly the best since FLCL. There's a part in episode 4 where one of the main characters turns into Ken of Fist of the North Star fame that nearly made me piss my pants. The sheer volume of references to other anime is amazing. Highly awesome.
on this one for sure. Lots of little details like the single frame of Pero Pero (the dog) from Kare Kano (His and Her Circumstances) right in the middle of Mune Mune's bouncing breast introduction in the third episode. Genius comedy!
