Extremely bendy model. (From Ridiculous poses.com.) I keep looking at it thinking that there must be more than one woman involved, but no, I think it’s just one extremely bendy woman with very high-heeled shoes on. It doesn’t seem possible that your body can do that, but it appears that hers does. Freak show.
Solid Potato Salad, anyone?
All you need to do that are the right shoes.
Meh. She has pointy knees.
Link for solid potato salad, for those who haven’t seen it. The interesting part starts about halfway in-- You’ll know it when you see it.
That picture is so creepy. When I was young I could stand on my feet and bend all the way over backwards until my head touched the ground, kneeling as I did it. However it helped to have a wall to balance on. I knew people who were more flexible than me, but no one that much. Ick.
And by “right” shoes, you mean “magic” shoes? Cause that’s what it would take for me to get into that position (I might be able to manage it if you actually broke a couple of my vertebrae). 
Sweet fancy Moses. The mind boggles.
So of course I am now wasting time on that website, and came across this. 
Just bend over backward. Then sit.
Anyone else thinking while watching that:
“Wow! Whaddya call that act?”
“The Aristocrats!”
Her belt is way too high.
Nah, I just think she has a long torso.
Cool! A blue cat guy!
What?
I had to look through the entire site after I stumbled upon it. Taking ridiculous modelling poses out of context and making fun of them amuses me, apparently. Funnily enough though, some of even the most ridiculous ones still have some stunning artistry.
Or this.
I’ve never literally seen someone with their head up their ass.
Well, her head isn’t technically UP her ass, just right next to it.
Mmmm… latex. She looks possibly underage though.
