Working a rivalry game, Friday night opener for both schools. I have visiting sideline. Close game. Deep pass from my visiting team to endzone on other side of field from my sideline. Both players go up for jump ball. No flag from BJ or LJ on that side. Incomplete pass...of course my coach wants DPI. As he runs out on field almost to numbers, I tell him.."Coach..you need to step back!". No response because he is YELLING at the top of his lungs..."Where's the flag???"
Me..."Coach...get back in your area"
Coach...(again at the top of his lungs where everybody could hear)..."WHERE'S THE F****** FLAG?"
ME....

I go out to tell my WH what he said...we go over to the coach..who is still livid...to explain why he got a USC. During the conference:
WH: "Good no call from my BJ coach. NO DPI"
COACH: "Well, whats HIS (me) flag for?"
WH: "YOU..yelling the F word!"
COACH: "Don't I get a warning??"
ME: "No...but I did tell you to get back"
COACH: "That's a bunch of s***!"
WH:

Coach spent the rest of the game in the locker room...and still couldn't understand why he got booted.
