Chapter 1 had that scene where characters were approaching the Student Council offices...
... and, of course, all savvy readers immediately expected to see a typical manga seitokai full of ultra-nice people who spend all of their free time working their asses off for the good of the student body...
... and instead we got to see four students get kicked out of the council room (literally, not metaphorically: the kick is so hard, they go flying out of the door) while Tsubaki yells: "And don't ever return, you losers, or yer gonna make me REALLY angry!"
It may be just me, but it's one of the funniest moments I've ever seen in a high school manga. ^_^
