Actually, cosquillero is right. First of all, like he mentioned, there are no toe nails. Secondly, the way the foot moves isn't a nerve reaction, the foot is moving because the stroke is pushing/brushing against it. A human foot, no matter how unticklish it might be, would never move like that.
I apologize, I don't know if you knew that or not, but I still appreciate the fact that you contributed to the forum. A majority of the population here wouldn't even give a second thought about contributing here so you are alot better than them. Thanks for the post but the tickling was fake, obvious or not.
