Always remind them that the TV fan has the advantage. Elevated, wide angle and slo mo replays. An eternity to second guess. On the field, one snap shot and one chance.
One of my favorites. Home team had just scored and went ahead by three. I have the Home Team sideline. One minute left. Pass on the opposite sideline 52 yards away. "Did you see that? Did he interfere?" "Did who interfere?" "That guy over there!" "That's your player coach!" "I know what's wrong with you guys, I just figured it out! Everyone of you wear glasses, you can't see!" I stepped back "Coach, you wear glasses too!" "OMG I'm as blind as the rest of you!" The clock ran out and we both were laughing as I headed for the locker room.
