Not at all, but I have had the pleasure of meeting one of your knights. Lancelot, as I recall. [Seems a bit distracted a moment] Hard to question the curious understanding hygiene when someone is that attractive and perfect in form...
[Blinks, and looks again to Arthur.] You and your knights are well known in my world, though only as fictional beings which would explain why your teeth aren't rotted and your clothes are far less filthy than they would have been had you actually existed. I also would assume that you probably come from a place where magic is indeed real, and Merlin actually was a wizard.
