Well little Timmy, since you were SO thoughtful taking the labels out of the cans, you are going to play canned flood roulette for the next week. This means, for an entire week you pick one can at random for your dinner, and you are not allowed to have another food outside of what the can offers. In the meanwhile, the rest of us will eat your favorite things in front of you, while you are in your sad corner eating your can of food. Me and your mother are going to place bets to see how long your spirit lasts. Let the games begin

My friend’s parents tried this sort of punishment mindset with him when it was a kid. He ended up grounded with increasingly draconian punishments for roughly five years because of the shockingly impressive stubbornness of all people involved until they “gave up on him” after 7th grade (yes, this literally started when he was a 2nd grader). He ended up moving out on his own at 16 and dropping out of school and didn’t really have a relationship with them for a good decade and a half.

I don’t really have any words of wisdom from this other than never underestimate a person’s ability to defy logic. It just ended up ruining the whole family’s experience for a long, long time.

Punishments are like the least effective way to convince/teach someone

For most kids, getting rid of something they like for a day or weekend tends to be enough of a punishment. From that story, tho? Parents were going waaaaaaaay overboard
