We had this substitute in High School who must have been on the sub roster because you'd see him at least once a month filling in for various teachers. His last name was Donat.
He was a nice, albeit small, thin, and quiet fellow - the sort that rowdy students could walk all over and not worry too much about repercussions.
We had him one day for Gym class and were playing floor hockey. I had a particularly wild gym class full of mostly hockey jocks, myself and a few other normies, and this hilarious special-ed kid who was known as Nurple.
Things descended into anarchy very quickly. All of the jocks just wanted to play pretty rough floor hockey and no matter how much Mr. Donat tried to organize them into teams or bring order to the class he just couldn't. It was pandemonium.
Finally, it was like one of those movie scenes where the quiet nerd character finally finds his inner strength and his voice.
Mr. Donat screams, "ALRIGHT. SIT. DOWN. NOW."
It was so abrupt and serious that it was like somebody hit the pause button in the room. Even the unruly jocks dropped their hockey sticks and we all formed this circle around Mr. Donat, sat, and listened. It was actually really amazing to experience - he took total control of the room in an instant.
What followed was a minute or two of him yelling rules and orders at us, explaining how we were being awful, and barking at us about the ways we would be subject to the principal and other things if we kept up and didn't listen. You could practically see the veins popping in his neck as he did this. He ended it with this tough-guy like, "GOT IT!? ANYONE GOT ANY QUESTIONS?"
There was silence for a moment or two as we all soaked it in and realized that he was the boss.
After a brief pause Nurple shoots his hand up and says, "UH YEAH, I GOT ONE MR. DONAT."
"What is it, Nurple!?"
"UH YEAH, IS YOUR FIRST NAME DUNCAN?"
It. Was. Amazing.
In that moment every shred of authority, every ounce of power and control that Donat had won for himself was violently ripped from him by Nurple's stupid but unexpectedly brilliant question. The class once again descended into anarchy as every single person was doubled over on the floor laughing and poor Mr. Donat was left standing there like a deer in headlights with nothing left to say or do.
I felt so incredibly bad for him because it was such a cringey moment, but something I will never forget.
