This series have superior jokes than K-on! and Lucky Star. But you need to have a good grasp of Japanese to get the jokes. Excellent voice acting (including ex-wife of Detective Conan mangaka) and great script/dialogue.

However many people here won't get it since they have to rely on translations which often missed the nuance of language.

the only subber is horrible, missed a lot in translation. my advice is learn Japanese then rewatch this gem again.

why complain? you not buying this show right? lol

Ayako translation is one of the worst I ever known. A lot of good jokes in this series got wasted by their horrible, literalist translation. It feels like they using Babelfish or Google Translate to translate this, seriously.
