A friend of mine took his wife to one of those self-defense classes.
One of the lessons was eye-gouging. The instructor told the women that if
they could get their hands near the attackers face, "Place your thumbs in
each of his eyes and push in until his eyes popped out of the sockets."
Then the instructor told them that if getting near the face was not possible
try to grab his balls. The women were instructed to yank down as hard as
they could.
Judi, seated in the front row raised her hand and asked, "If we yank hard
enough, will that pull his eyes back into their sockets?"
