I think you misunderstood the question. It used to happen A LOT. If you don't remember it, you've dated yourself as being fairly young. If you do remember it happening, you date yourself some as well. I'm in my late 30's and I remember when this used to happen.????
I don't recall the refs taking a time out or giving us (or anyone for that matter) a penalty for crowd noise. That would be stupid!! The red hat ref is the TV ref and he comes out often during CBS games, more so than ESPN it seems. We all know how CBS LOOOOOVES them some commercial air time ($$$).
