This is highly disturbing. Someone was actually searching for "what ways can i get my sister nad brother to have sex" and the first entry in the search results is my blog. Check this out:
Why the hell would anyone want to get their siblings to have sex? Crikey! Let me say that my blog does not encourage inter-family sex ok. Incest is bad, bad, bad unless you are an animal like the bonobos who practice sex between closely related individuals as a means of dispute resolution or greeting. Ha! And to the dude who was searching for this, you seriously need some help mate.
