How weird (cool) is your body?

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

I meant in handcuffs.
A field test, so to speak.


Let's see...
I have a BMI of 17.5.
I can run a 6 minute mile.
I can run a 7 minute mile backwards.
I can do 30 pull-ups straight.
I can do the thumb-popping thing, too, which helps a lot at thumb wrestling.
I can only wink with my right eye.
I can snap using my chin and elbow.
I obsessively crack my knuckles.
