Dr. Yoda said:
I don't know about you, but I find that incest is one of the most erotic forces God has put upon the Earth. If it's possible for man to do it, then why would God have created it and asked us not to do it? It's like swearing. Man tells us we can't swear but God has put those words on the Earth, for Man to use! Why would he give us hands and tell us not to rub our genitals???
God was drunk when He sneezed.
