I am double jointed at the thumb and I can make my shoulder blades stick out. I really wonder how the heck I do the shoulder blade thing. Oh and I can bring my right leg almost behind my head.

I can recite the alphabet backwards, though I guess it is not that hard.

OH! I can read and walk at the same time without running into things or getting myself injured. Though once I did not noticed the ambulance until I was in front of it.
