I read that before. It's a good 'un.
It borrows pretty heavily from an older Mickey Mouse story, though. Dunno how that one goes, I've never read it, but that is what I hear.
I love these things. Not because they scare me, I actually cannot do that, but because the well-written ones are really engaging.
Of course, the terrible ones are hilarious (THEN WHO WAS PHONE?), so there is really no way you can go wrong.
Creepypasta is like fanfiction. When it is good, it is REALLY good. When it is bad, it is terrible. And wonderful.
