What's The Score Boys?

Deciding to catch the second half of Perpignan v Ospreys rugby now the racing has finished on TV, I was amused to hear the wired up ref ask his touch judges "what's the score boys?"
Not as unusual as you might think that the ref doesn't know the current score. Whenever I had official linesmen I always instructed them both to keep score - you'd be surprised that with everything else that can go on in a game how far down the list of priorities the current score could become and in a tight game I would quietly check with them both as the closing minutes approached...............and you'd be amused to know that just occasionally their calculations differed!
