I really enjoyed the first episode.
The comedy just pushes all the right buttons for me and we didn't meet any annoying characters or characters with annoying voices so far (the tiny living bloomer...thing is weird, though).
The highlights of the episode were of course the train scene, Najimi trying to sell the book and the scene where the announcer tells Najimi to get off the table as it's dangerous to stand on it. Oh, and the Panty Revolution!
Also, it really seems like Hiroyuki has a thing for lolis and bloomers.
