1) I, as the head coach, got kicked out of a game for arguing with the ref about being flagged for coming on the field. A player was hurt. He didn't believe us. I was right and had evidence after showed I was right and so I was reinstated.
2) In a 7on7 tournament, the refs called a TD on a final play to win the game. Even though the kid both was not in the end zone AND didn't catch the ball (like, not just it touched the ground or something, like he literally did not catch it in any shape or form). I chased the ref down after to show him the video. Admittedly not my finest moment.
