POINT 1:"Scoreboard" is a response, not a initial attack.
For example, if zoobs magee starts running his gums about attendance, or 1984 etc., then the recipient of this unsolicited attack can end the exchange quickly and irrefutably with "scoreboard" if it is at his disposal that particular year.

POINT 2:"Scoreboard" only works when the game is over or clearly out of reach.
I had to laugh when some kid dressed like J. Crew himself, sitting 6 rows in front of me at the game this year, and with whom I had no interaction at all to this point, turns around after a BYU score in the second quarter and yells "scoreboard" at me. Really? The game wasn't even halfway over. He also broke rule 1.

Was that you Mesa?
