I'm not sure of this, but does he appear in "House Inputs and Outputs" (https://xkcd.com/2963)? It looks like he's the one who says, "Do you think I scratched the paint?"

@Calibrate At https://www.explainxkcd.com/wiki/index.php/2963:_House_Inputs_and_Outputs it is just called a voice, so I don't believe it counts.

Explain xkcd is a wiki dedicated to explaining the webcomic xkcd. Go figure.

True -- it also looks like it may be White Hat at second glance, too, so it's hard to know for sure!

Description text has a typo btw - it says "Black Hat" instead of "Beret"

@binarypigeon Thanks, I was being a little lazy
