Gintoki and Yamazaki in “Unfinished Business”

That is the case, so excuse me. You seem to be someone I used to know, but I don't remember. Uh, Shinsengumi's... what was it? Should I call you Shin-chan maybe?

[hits Gintoki on the head] Hey! I said it was a secret operation, didn't I?! Ah, I said it! [drags Gintoki off to the side]

What is it, you? Bang bang banging on people's heads like that. Are you hoping to become a tambourine player? If you don't like Shin-chan, then how about Sen-chan from secret operation?

Are you harassing me? Am I not telling you that it's Yamazaki?

Oh, I don't remember, so I will go with Tanbara.

It's not that you don't remember, it's that you don't want to remember, isn't it!!
