I remember years ago I was working a game in a "Private-Christian" conference. They gym was not very filled and the visiting team had a call go against them on the other end in the first half. Well I was the Trail, near the bench and 5 coaches started yelling at me (I did not make the call).
I simply said, "Coach, I will answer any question you have, but I am not listening to 5 people yell at me when you are not saying anything. The HC turned around and said, "Will you guys shut the **** up!" I did not hear a peep out of the entire bench the rest of the night.
Peace
