So - we know that Howard has a habit of hating stuff on air which he secretly likes. Browsing youtube, and ran across some nasty Siobahn videos. The video where it came on after the surgery had some telling signs in the beginning. He made fun of Siobahn for having man hands, and an obsession with cats. I submit this as further evidence Beth was once a man. P.S. Siobahn's daughter was hot (22 minutes in).
