How weird (cool) is your body?

Your shoulder's double-jointed.

People say this is weird, but I don't think so. I can bend all my fingers minus my thumb back to make a 90 degree angle.

I thought I put that in my post. Derp. Yeah, I have double-jointed shoulders.

I'm surprised you haven't had a chance to test this out before.

I've obviously tested it out before seeing as how I'm aware of the fact that I can perform this act.
