has unveiled the second installment of their de facto infomercial for the Screech sex tape, complete with a new clip from the video featuring Dustin Diamond's "co-stars." Luckily, their faces are pixelated, their voices digitally altered, and are only vaguely described as "from the heart of the Midwest and in their early 20's," which should at least temporarily forestall the unprecedented shame they will experience for accepting a gig that even the most emotionally ravaged porn star would refuse for the purpose of maintaining some elemental shred of dignity. (TMZ has also helpfully included celebrity smut-puddler David Hans Schmidt's entire promotional itinerary, so you'll know where you can next catch him hawking his wares.) As an alternative to the new preview footage, we offer this clip of SNL's Weekend Update coverage of the story, which while not all that funny, at least makes us feel less complicit in assisting Diamond's attempt to ride a Dirty Sanchez back to semi-fame. Isn't even a highly theoretical sex act sacred anymore?
