I dunno. Probably pointing out valid objections to a definition, e.g., Plural definition of a singular term {mea culpa}) sHould probably be avoided, but comments like (I've been in the business for twenty years and I've never heard the term) could easily be bluffs and should be interpreted as such by all players. I think of the days when Milo (we miss ya, bubba) would rant on about this that and the other thing and there weren't enough grains of salt in the whole universe to swallow them all. There should be some restraint here, but banning extra comments entirely is not, IMHSHO, warranted.
