How many coaches have you tossed?

[OhioASADistrict1Commish]

I have been a coach, umpire and tournament director. After many years from each position I have had the opportunity to watch many games.
I would like to know what the average number of coaches that you have ejected from a game over the course of a year, or 5 year period. Please state if this was high school, rec. ball, tournament games or something different.
If you have tossed a good number of coaches, what was the circumstances?
