i can:
-lick my elbow
-touch my elbows behind my back
-cross my fingers to below the middle knuckle without assistance from my other hand (if that makes sense.) As in, i can give you the finger with my pointer wrapped around the middle one.
-the thumbs-up toe thing
-i have an apposable (opposable?) pinkie toe
-my elbows bend the wrong way

and other stuff to hard to explain
