I searched these boards and I think this one would be categorized under "police."
There was (and still is) a tag attached to pillows and mattresses:
DO NOT REMOVE UNDER PENALTY OF THE LAW....
and it's got some other gibberish after that.
One day when I was four, I tore the tag off the mattress.
I waited in fear for cops to come.
I thought somehow there would be some sort of "signal" that let authorities know that SOMEBODY did indeed remove THE TAG under PENALTY OF THE LAW....
But no cops came.
I threw the tag away in the garbage and hoped I wouldn't get into trouble! HEE!
