For those who have not read the manga here's a link:

What I enjoyed about this manga was that it handle a taboo subject with humor and it had a sort of quasi-realism that is very rare when it comes to sadomasochism. Instead of the whole slave and master fantasy that has been play out in so many adult manga we get two silly goofballs messing around with collars and ropes.

So I guess what I'm looking for is a manga that deals with kinky or taboo subject matter in a lighthearted and fun way. Up till now I've also read Sundome and Domina no Do. Sundome is absolute riot with interesting characters and wonderfully wild and funny situations. Domina no Do on the other hand came off rather flat and uninspired.

Ai Kora about strange fetishes.
Oretama about sex
Yuria 100 shiki about sex (this and the one above are more about stupid/fun. Really not clever or witty as you asked, but I thouht you probably wanted to check it out.
NHK about Hikikomori.
Kami no Mizo Shiru Sekai about 2D girls? Maybe, I don't know if it's what you're looking for
Last is: Sei Oniisan. I know this could be a real weird suggestions, but it deals with religious characters in a funny and witty way, so I thought it could be included.

What I like in Trivial Pursuit style. Pick your category:[img]http://i379.photobucket.com/albums/oo233/Reid4891/Manga/trivia-1.jpg[/img]

Well Thank you reid1, I've read Yuria 100 and NHK but the other titles look promising.

All I can think of is Kanojo wa Kanno Shosetsuka it is also about s&m and has its funny moments
