Funniest Manga You've Read?

Recently I read "Bye Bye" and was just laughing my ass off at all the misunderstandings. Most if the time misunderstanding piss me off, but for some reason it really got me. Maybe because they were all pretty inconsequential, or because they were so absurd that all I could do was laugh. Also, the author was so good at drawing a variety if facial expressions that it was visually comedic. Not the funniest I've ever read, but definitely one I got some big laughs from.
