[just another ref]

This is one of those things I have been doing so long, I don't remember starting it. I blow the whistle, then, all in the same breath, spit the whistle out and say, emphatically, "No shot!" My idea was, if I do this quickly, no one can accuse me of waiting to see if it was going in before making the call.
Now I learn, in that other thread, that whether it goes in or not is significant to some in whether it was a foul or not. I still don't get that one.
