This is, without a doubt, my favouite comedy series of all time. The characters (particularly Becky, she's so adorable), the silly stories and situations they get into, the interactions with the other three classes, Kami-sama (nya), everything, it all just works flawlessy to create a heart-stopping series of godlike proportions.
Oh, and Himeko has got to be the best airhead character ever (even better than Osaka, and that's saying a lot).
lol, and the aliens are the best
