Ah, you too! - I thought I was the only one :-D

For me, it's the eyes and mouths that creep me out, they always look as if they're planning something creepy between them (especially the group shots).
A bit like those creepy dolls with a switch on the back of their head to make the eyes move :-P

And they always have that unsettling grin!

If these creep you out then never, never walk into a room loaded with porcelain dolls.  My mother used to collect them and she had a room full of them.  You always felt like you were being watched.  Enough to make your skin crawl.
