The top3 most hilarious interactions for me: Hitoha&Yabecchi, Mitsuba&Shin'ya, Mitsuba&Sugisaki. These 3 chapters have them all in one way or another.
Mitsudomoe, volume 12, chapters 214-227 A little note: Japanese sentence doesn't really require the subject (which is mandatory in (proper) English). In fact, more often than not, the subject is only implied; the sentence structure usually doesn't have dependancy on the person (meaning that, for example, "I say", "we say", "he says", etc all will sound exactly the same). So, due to the missing outspoken subject in a number of sentences in ch.214, Satou's father thinks Ogachin asks him about Shin'ya, when in reality Ogachin asks him about himself (i.e. Santa).
Damn, still no raws for this month's Dogs and the latest Mitsudomoe chapters 225-226...
