LOL, that's my sister's hand. I cropped the pic, to use as an avatar, but the full pic showing me and my sis is in my "Friends and Family" album on my profile page.
I don't have one of those programs that lets you edit a pic, otherwise I would blot her hand out, just for that pic.
Looking at it - it does seem to be a hand from out of nowhere, or sprouting from my ear, lol. We were posing for her daughter, who wanted a pic of us together.
I've been thinking of putting another pic of something else as my avatar anyway. Maybe one of my fat ADFs. They are soooo funny and are much more photogenic, lol.
