What is creepier than a centipede?

My niece just posted on her FB wall that “nothing creeps [her] out more than centipedes”.

So I’m looking for suggestions here. Humor is all I want, but even serious-creepy things are welcome. I’ll put the best of the suggestions on her FB wall… and she’ll probably never be creeped out by centipedes ever again. She’ll have a whole list of creepier things.
