Childhood has many defining moments, and I'm a firm believer that one of those moments is something on TV scaring the living shit out of you and changing you forever.
So, in the spirit of sharing, we'd like to know which TV moment scared the living bejeezus out of you when you were a kid.
Maybe the moment Slappy came alive in the Goosebumps TV series still haunts you to this very day.
Or maybe you've arrived at the conclusion that you'll never be able to forget about the white floating head in Courage the Cowardly Dog.
Or hey, maybe it was something that wasn't necessarily supposed to be scary, but still gave you the heebie-jeebies, like when the Tubby Custard machine broke in Teletubbies and just kept overflowing.*
So let's relive all of these fond, terrifying memories together! Tell us in the comments below what TV moment made you sleep with the light on, and why it shook you to your core so much. We'll feature the best responses in an upcoming BuzzFeed Community post!
