Here's one for you, R133:
When I was in the second grade near the end of the school year, Mrs. Smith decided that since we were studying the Knights of the Round Table, we would put on a little play and the principal offered to videotape the production (which was very exciting as VCRs were new; it was a U-matic deck, the kind they used professionally and the district had purchased one for each school). I was cast as one of the knights. When it came time to make costumes, we didn't know how we were going to make helmets and I came up with the idea of using the cardboard gallon iced cream buckets and covering them with tin foil, cutting another piece for the eye guard, the whole nine yards. It was pretty cool. The rest of the costume was pretty basic black pants and shirt with a shiny material she cut to wrap around our bodies and secure with a rope, but since I'd conceived the idea of using tin foil on the helmets we used it on the swords too.
Mrs. Smith went all out and we had rehearsals, worked on it extensively, and all of kids in the class were very excited about the whole thing. The day before we were to present the entire production for video taping, we went out for recess and in my excitement, as I exited the school I jumped off the landing (which was all of three steps above the ground level) and yelled "Weee!". Mrs. Smith went ballistic, screaming at me and calling me all sorts of names, and said (and I recall this very well) "That's it, you're off the play!"
I was crushed. And she held to it, assigning my role to another boy in the class who fit in my costume. There wasn't much to the role beside standing around and joining in the chorus lines, so it wasn't like he had trouble learning the part in less than a day. My father, ever the bad parent, refused to go to bat for me and told me I deserved being kicked off the play... for yelling "weee" and jumping off the landing, something that all the kids did every damn day, just not in sight of their teacher.
So the play went off, my replacement played my part, and the video tape was submitted to the district to show what the school had done with the new equipment. The district superintendant was so pleased they copied it and send it to all of the schools in the district where it was shown to all of the students in each school. The principal received accolades, so on the last day of school for the year he had an assembly where they awarded the actors and Mrs. Smith a special commendation. My replacement was separately called to the stage and singled out for costume design specifically for cardboard helmets and swords covered in tin foil.
I burst into tears and ran out of the assembly room. Everyone (except the principal) knew why I was upset. Mrs. Smith followed and admonished me for acting out and made me return. She told me to be quiet when I said "it was my idea to use tin foil for the helmets!" and told me if I said another word I would have to spend summer break in detention (which was not a thing, but it scared me enough to not speak out).
When the final report card arrived in the mail a week or two later, Mrs. Smith had given me a poor citizenship grade with a handwritten note that it was time to grow up and accept responsibility for my actions. Suffice it to say I never participated in school dramatic productions again.
