Gin Tama

[before the episode proper]

Gintoki:
[voice-over] Teach us...

Class:
...Ginpachi-sensei!

Gintoki:
Um, this one's from someone called Kutabare ["go die"] Oonishi. 'It looks like Gin-san is always wearing the same kimono. Does he only have one set of clothes?' Okay, here's your answer. The truth is, he's got four of the same kind of kimono. When one's in the laundry, he wears another. Huh? You want to know why he has four of the same kind? Well look, it gets too boring if the protagonist keeps changing clothes. People like Lupin are always wearing the same coat, right? Anyway, in an anime, it's too tiring to keep changing clothes, so that would be a problem. Now you, Oonishi, go stand in the hall!
