Ok, this is just plain disturbing. Look at this:
I'm not sure if it's the eerie accuracy of his vocal impersonations, and the fact that that timbre and depth simply looks like it should not be capable of escaping that set of vocal cords. Or the fact that my brain horribly keeps attempting to synch what's being heard with the original music still playing in my head simultaneously. Or it's the strange plasticity of that boy's face, as if he was really just some sort of semihuman automaton, lulling us with these cheery jokes before ateempting to eat the very flesh off our skulls.
Look again:
This shit scares the crap out of me, man.
