At what point do you engage/remove an obnoxious fan?

[SWMOzebra]

My one and only fan ejection in a high school game was in February a couple of years ago.

A big ol' fellow in a John Deere hat and overalls was sitting on the front row of the bleachers during the GV game (his daughter played for the home team). He didn't say much during that game, but he was extremely vocal during the BV game (home team was bad and routinely got thumped by 30+ points that year) ... nothing vulgar or racial, just complained loudly about every call (or no-call) that didn't favor the home squad. My partners and I had done a pretty good job of ignoring him.

Then about 1 min into the Q4 the ball went out of bounds right in front of him and the T awarded the ball to the visiting team. As I stood there in front of him waiting for subs to enter the game, he said "You boys are about the dumbest sons a-b!itches to ever put on striped shirts" loud enough for those around him to hear.

I called the principal over to where I was standing a informed her he was to be removed from the gym before the game could continue.

He still sits in the same spot for all the home HS games and I see him several times a year ... but now we joke about it!
