Same here.
Back in high school, among various shenanigans, we figured out we could lock our class out by jamming a pencil into the lock and breaking it off, which we did the day of a math midterm. There was a metal frame on the door which opened in, so they couldn't even take the hinges off.
Such a dumb prank but extremely effective. They brought the janitor down, he couldn't figure it out, which isn't his fault, he isn't a locksmith. They probably had to hire an actual locksmith, but they did not get the door open that period and we achieved our objective of postponing our midterm.
Because I am an idiot, I mentioned that story to a lacrosse team I was coaching in approximately 2013. Two days later at practice I ask where is Jerry? (Our goalie)
He tried the trick, got caught on camera and got suspended.
But credit to Jerry, he didn't snitch.
