Is Barbara Bush The Illegitimate Daughter of Alestair Crowley???
Hell, no.
Okay, now that I've completely declared my bias on the subject, I'll point you to an article recently posted at the Smirking Chimp that goes all conspiratorial about Barbara's mother supposedly hanging out with Crowley nine months before Barbara was born. It is a convoluted route to get her there, and all based on an anonymous source, a sixth-level initiate in something called the Ordo Templi Orientis.
Anyway here are pictures of Barbara, her father, and Alestair:
To my eye, Barbara looks too much like Marvin in a white wig to be anyone but his daughter. I would do anything for Bush hatred, but I won't do that.
Update: Fixed the title, since this post has been linked to by Jeff Rense. Welcome, welcome, one and all. Boy, of all the people who would link to me, I never thought it would be Rense.com. It's a wild wild world.
