Some humans are especially obnoxious, case in point, this guy. Strange just laughs as Sans mentions a lesson in humility, a short bitter laugh before he starts bitching and moaning.

"Humble? No, this isn't 'humbling' by any means, there's nothing humbling about me being denied my magic. It's inconvenient, needless, and absolutely horrible." His tone is tight and tense, as if he's just about ready to go on a rant about how this place is awful, the experience is degrading, he doesn't even have arms, and so on and so forth.

"You can't even move by yourself! How is that humbling?"
