I had a shop teach that would slam an iron pipe on a steel desk. That got the attention of all boys, girls, and penguins. But it was usually all boys. Or shall I say, it was usually all persons with penises.
I had a theater/performing arts teacher who would holler "Idiots, on stage!" for the men's chorus, and "Heifers!" for the women's.
He'd be so fired in the modern PC era.
He was a Marine with grunt experience in VN. He didn't give a damn what anyone thought of him, his "teaching style", or pretty much anything.
He also made it really abundantly clear that Directors in the performing arts don't give a crap about your feelings, or need you on stage, and can replace you before you've even packed your crap and changed back into your street clothes.
He inspired more than his fair share of folks who ended up on Broadway and the performing arts. If you look carefully you'll see a glimpse of him in the chorus of the West Side Story movie.
Everyone I've talked to since those shared experiences 20+ years ago harbors no ill will toward him nor pretends that they were "offended" back then by it. In fact, to a person, he is always mentioned fondly as a teacher who really DID care enough to give a realistic view of how hard the performing arts can be on people emotionally and how rewarding putting on a top notch performance is.
I thought he was going to chew my ass midway through "South Pacific" when I had a bit part of the clerk who comes into the Officer's scene carrying a big stack of reports... On Wednesday night of a week long run, I tripped as I entered the set, and the pile of "paperwork" as a prop was instantly scattered across half the stage.
I was immediately in shock. Our cast had some very talented folks and they went into ad-lib mode instantly. "Ensign, PICK UP THAT MESS!" which is exactly what I did while they made up lines, and then, "Ensign, a-ten-HUT!" (I went to attention...) "Why are you in here making a mess of my office?! There had better be a dammed good reason!"
Yes sir... And back into the lines...
He came backstage laughing his ass off...
"You guys covered that PERFECTLY! PROPS! Staple that damned pile of papers together before tomorrow night, so KLUTZ here doesn't have to clean them up off the stage when he falls down again! Good job, guys! Chorus, PLACES!"
And he stomped off to check on whatever else needed done to finish out the show that night...
Great guy. I hope he's enjoying retirement.
