Way back in the hazy days of old, back when I was but a novice to the world of gaming (yes, with the dinosaurs) I vaguely recall a paragraph in the original v1 of the AD&D Dungeon Master's Guide which suggested something to the extant of "If there's no rule for it, make it up and keep the story moving, and make sure everyone is having an enjoyable experience" or whatnot. That disappeared in the later versions (thanks Unearthed Arcana), and the Rules Lawyer was born with the oft-repeated mantra of "Show me exactly where it says that I can/cannot do that!"
And no, this was long before WotC or Hasbro came along. This was TSR starting to rot from the inside, even long before Gary was dethroned there.
