Have you ever just stood in a room in Morrowind and heard the crazy things the NPCs say? I once was walking through the Ald'ruhn Mages guild when I heard an NPC say "I shouldn't have pushed so hard". I was thinking, "Wait, what?!" Then I started to notice everything else, such as in Mournhold a Royal Guard (or maybe it was a High Ordinator) saying "Is it just me, or did she put starch in my shorts?" This is not a joke, I have actually heard someone say this in the game.
So: Any curious/strange/weirdsthings you've heard an NPC say?
EDIT: Actually, after hearing it again, I realize it was "Good grief. Did she really out starch in my shorts?"
