What is the worst form punishment you've received as a kid?

Mine was writing a verse from the Bible 2,500 times.

Being subjected to days out with my parents and uncle. They were always a fucking misery.

It wasn't even a punishment, he just treated me like shit and parents were too spineless to say anything.

That's ... Pretty bad.

I can't think of anything original, just the usual asswhopping from mom. My dad would just yell at me and then explain why what I did was stupid later.
