Boys' varsity game (non-conference) this past season: My partner blew his whistle to report a foul that occurred in the act of shooting. I immediately froze and watched all the players on the court. As I slid around the players to the baseline, to get them ready for the foul shots, I heard my partner report a time out. The players never made it to the foul line nor did the shooter.
I had no clue who he was!
As the time out expired, I learned that my partner didn't either.
Evaluator's grade for us on dead ball officiating? A solid F!
