Danna ga Nani wo Itteiru ka Wakaranai Ken has been a very pleasant surprise for me this fall season. While it definitely delivers in bunches with its otaku-centric humor, I think that any anime fan can find plenty of laughs here as well. I love the relationship between Kaoru and Hajime, and in 3 minutes, you couldn't ask for more. Also, Kaoru-tan is one of the best girls of the season. Science.
Gave this a go on a whim, thought I'd hate it but it turned out to be very nice and sweet. The episodes are short enough to blast through pretty quickly anyway, but a rather pleasant watch :)
I'm just going to say that the first two episodes were really terrible but then it luckily turns around to less obnoxious otaku humor. I think it works best when it's just about the couple's relationship. With just three minutes per episode it's not much of a commitment anyways.
