Chewing wasn't part of the bet. I'd break my teeth. [Not that Sans uses his teeth to chew... That's not the point, okay. He is just the picture of innocence right now, except for how this is Sans and he doesn't really ever look innocent.] Tasted like metal. [Sans has tasted metal before, so he's just going to go with the safe option.] How do they taste to you?
