I just love those ortho-bloopers! They had another good one when Barnabas was about to put the bite on, I believe, Vicki in the patio until somebody interrupted them. He shuttled off to the side, turned his back to the camera, and defanged himself. Now we know why vampires need human blood to survive. If they depended on corn-on-the-cob and spare-ribs, they'd starve.
