I guess an "L" for... I don't know. I'm just guessing.
I used to watch Courage the Cowardly dog. Oddly enough I was always worried I'd get nightmares from it. Also, I remember being really scared of the stories o.o
I loved the stories. Then again, I grew up on things like "Tailypo", "Haunted Appalachia" and "Scary Stories to Tell in the Dark"
(Not to mention my mom had a good number of personal horror stories)
