ROFLMAO! I about spewed my coffee all over my keyboard just now thru my nose. That was funny. No, that stuff happens to trainees in bootcamp. I was in a line outfit and we had to be ready to deploy. Fast. I lost buddies in Grenada, Panama and Somalia. In fact I had buddies killed during stateside TRAINING exercises. It's a dangerous line of work. I treated my troops firmly but with respect. I do the same with my students.
But actually, years ago, I did use to make my high school students do pushups when they were late to class. The athletes and JROTC especially. Anybody that age can do 25 pushups without breaking a sweat. But I'd add 5 more for each additional tardy and sometimes I'd make them put their feet on my desk and do them ranger style (elevated). Sometimes, I'd even get down and do the pushups WITH the kids which was great because it showed them I was in half decent shape, too. That hasn't happened for the last 10 years but I could do it now, after my gastric bypass last summer and now having lost 130 pounds of fat. I'm about the size I was in the army.
Anyway, after awhile, I'd hear them smashing down the hall like they're trying to break the opposing line and screaming: "I gotta make it or it's 150 with my feet up! and they'd DIVE thru my door as the bell rang. After awhile that got to be hazardous to other students in the halls so I relegated that joy to the coaches or JROTC since those were the most flagrant offenders. Young ladies would often just have to stand next to their desks. Doesn't sound too tough but standing in HEELS for 90 min can get painful. That worked for years but when parents started to complain I read the liberal writing on the wall and stopped completely.
These days I just show them my military photo album or I give them a youtube link to the videos I upload of my IDPA Shooting matches. Sometimes I give them a link of one of my AIKIDO classes I have filmed. That's pretty convincing evidence that this is a teacher you don't really want to mess with. Oh and the teacher attacked last year IS suing. He's suing the school for not having any security available on the floors after school. That situation has now been corrected so if I stay late to grade as I usually do, there is at least some security around. Not that I really need it myself, but there are other teachers who do. The kid and parents who were the attackers were arrested but I don't know the outcomes. It's only a 3rd degree felony to attack a teacher so probably not a whole lot. Hardly worth the effort to sue them, they don't have anything to take as punishment.
Don't I know it brother. Stay safe.
