Not only is the show a friggin' hilarious blend of Azumanga Daioh/Cromartie High School/Pani Poni Dash, but the song is sung by THE Hyadain. Don't know who he is, well
you should educate yourself quick, because I think it's pretty awesome that he's now singing anime openings.
Everyone watch this show. Everyone love this show.
