Great! Could you? Don't forget to vote in the poll I started for the same reason: http://cutedeadguys.net/threads/27977-Can-you-pull-up-your-balls-at-will.
So far, most members say they can't.
I can, with effort, lift and drop them at will several times a minute (no hands!).
It's kinda like being able to move your ears (I can't, but my father could voluntarily move his ears in amazing ways).
I guess we could learn if we tried (but who needs it??).
