This isn't the scariest video ... this one is, true to its name, creepy. All the videos we watched were by Fewdio, and the absolute scariest is called Bedfellows. Seriously, don't watch it unless you don't want to sleep tonight.
Here is Creep, the second scariest video that I saw yesterday:
I'm sorry if I've ruined anyone's sleep. SERIOUSLY DON'T WATCH BEDFELLOWS!!!
And I promise I'll be back to posting happy things on my blog soon.
