User blog:InvaderrrZIM/Need help remembering a TV Show!!

Ahhh, so another thing from my childhood is killing me. There was this old scary thing (not sure if TV Show or movie), but it scared the poo outta me when I was a kid. Like, I was afraid of going anywhere alone.

So anyway, the story is like...there are these five kids in detention or something? And some old teacher person is taking them out one by one, leaving messages like "Four left to go", "Three left to go", etc. depending on how many of them are left. And it ended with some girl opening a trophy cabinet or something, but she couldn't find the right key so the old teacher person gives her the key then leaves. Or something...

Sorry I don't remember much, if any of this sounds familiar to youse guys, could you lemme know lol? Not being able to remember/find anything on this is driving me crazy!
