I was handed detention only once in high school. I don't remember what for, but it was some political bullshit with the teacher in question who didn't like me, so there was no actual legitimate reason.

As part of the busywork they force you to do there you had to fill out a form and complete a writing prompt which asked, verbatim and in full, "Explain in your own words why you are here." This was supposed to be punishment. Well, these dumb half-literate motherfuckers weren't smart enough to include some important context in that prompt, so I started with the big bang and worked forward from there. I filled both sides of that stupid photocopied piece of paper before the detention monitor stopped me an kicked me out early.

I assume word got around about the smartass, because I was not given detention ever again. I suppose they figured out it wasn't effective on me.
