[His nose screws up in a bit of a sneer, when, of all people, some old guy answers his question. Badly, he might add. White hair, curled and in a messy style on top of his head. Eating a handful of what, candy? Must be nice, being able to snack constantly when you have dentures and not real teeth to worry abou--

...Ah, no. He blinks once, tired-looking eyes squinting at the man as he gets a better look at him than his first glance. Despite the pale hair and deep voice, this guy... wasn't actually as old as he'd thought. Pale hair like that, he supposed, could be related to a quirk, after all.

He tips his head forward, as if to get a better look at the man--his gaze looking a little bored as he examines what the hell the man was wearing. A yukata, in this day and age? Maybe he was into cosplay, he thinks for a moment, before he lets out a quiet, huffing laugh.A smirk that pulls at staples that appear to be holding his face together.]

If something like that 'got me going', I'd start to question myself pretty heavily, old man. [The drawl to his voice is apparently very purposeful on how he pulls on those last two words. Trying to get Gintoki's goat, apparently.]
So honestly, I'm still looking for a punchline.

Do you have one, then?
