Lol. It's like Monty Python and the Holy Grail.
"Must be a noble."
"How do you know?"
"'s 'cause 'e ain't got $#@$ all over 'im."
These ain't nobles. They's adventurers. They ain't right without filth and gore on 'em.
I'm only partially joking. I mean, yeah. They could tame it down a bit. They do seem to ALWAYS be filthy.
