Still more Faces

I'm starting to feel a little paranoid. I'm seeing faces everywhere. :-D

Is Big Brother watching me?
I dropped off our granddaughter Klarissa at the daycare one day and spotted this interesting little cactus cluster (prickly pear). Most of the pads have a face on them.

I think the owners scratched the faces into the pads which later scarred and formed the faces seen here. instead of scarring, one had began to rot, thus leaving the one with holes.

So am I paranoid? or is somebody watching me? :-O
