The PC Handshake

I didn't want to hijack John's last thread, but it reminded me of a really bizarre dream I once had. The dream started out with my mom calling me because some militant lesbian feminists were holding loud meetings in her backyard, and she wanted me to come help her get rid of them, not so much because of the trespassing as the fact that the neighbors would think she was also a militant lesbian. So I drove on down there just as the group was packing back up into their cars. I went over and introduced myself to them, offering my hand as is customary for such introductions. The leader of the lesbians shook my hand, but dug her thumbnail into my thumb, drawing blood. I asked her why the heck she did that and she responded "my hand got scared, so it bit you." She then elaborated that the standard handshake is an instrument of male dominance, and the thumb commits a penetrative, symbolic "rape" when it crosses over onto the other person's hand. She then informed me that the correct way to shake politically correct hands was to keep the thumb directly over the rest of the hand and just rub palms together.
Unfortunately, that's all I remember of the dream.
