I've just started watching this rather surreal IMO anime. I thought the episode where Hideki is trying to teach chii the names of things, and chii constantly points at Hideki saying Hentai, Hentai, very funny.
I've seen the anime but I like the manga much better. I think that the manga has much more detail in it, and the anime changed a few things and added a few too.
I like the episode when Hideki tries to teach Chi to bathe and Sumomo comes up with the game show and stuff and then Hideki says something like "if you're still confused just copy the people around you" and Chi ends up in the mens bath and hideki's like "Chi what are you doing here!" or what not and Chi tells him he told her to copy people around her so she copied him...
