Hey, i was toying around and trying to decap uke for the pure fun of it... until my charcater dropped something he really isn't suppose to be dropping !
of course he had to get it back !
makes for a funny bloopers !
Oh lol, i've had that happen to me several times as well. It's because your head rockets forward with great speed, and when the neck doesn't allow further movement, it snaps due to the amount of force behind the head. Kinda like a whiplash.
