I managed to get a clip of JD doing a push-up. It shows the back a bit.

He's got back hair.... manly!

yes thats a good one thank you

wow dj thats awesome thank you

Now, what we need are Wireless servos to get rid of all the wires. Of course, then J.D. would not have any back hair. Then he would have to get in touch with his feminine side.

Seriously, D.J., do you think you could invent a wireless servo. It would make you filthy rich!

or you can cut off your beard and use that as hair haha

I guess so.
