I FUCKING LOVE THIS EXPRESSION ON EREBUS.
In his modern day variant, he works reluctantly as a pediatrics nurse during his day job. (At night, a ruthless torture expert/mercenary)

He really isn't fond of snot nosed little kids. And they aren't usually very fond of him, which forced him to act like an idiot by doing a little puppet show for them to cheer them up. It makes him feel stupid, of course, and by the end of the day he's just a big fussy pile of grumpiness.
