(Slight) hijack:
Had a coach who was behind use their last TO with about 3:00 left in the 4th. As they break the huddle, I let him know that was their last TO.
Coach: "Any way I can get another TO?"
Me: "You do get an additional TO in overtime."
Coach (while looking up at scoreboard): "Know any 27-point plays?"
Me:
Anyway, like Scrappy mentioned - short and sweet. Mention the bonus situation, the additional TO's, make sure the time added is correct, and away we go.
