TMZ.com has obtained (read: been given a copy of by the celebrity porn broker who's trying to sell it, and who's interviewed alongside the clip) a preview of the Screech sex tape, featuring 42 seconds of star Dustin Diamond soaking in a bathtub and then describing one of the video's featured sex acts to the camera. (Yeah, probably the Dirty Sanchez one.) For now, we can deal with the mildly scarring sight of Screech reclining in the tub, possibly in the early stages of sexual arousal. But we know that we'll eventually be required to watch the full video when it's eventually "leaked," a psychically scarring ordeal that will almost certainly permanently replace our happy, innocent memories of the Saved by the Bell gang sharing plates of French fries at The Max with nightmarish images of an imposingly bedonged Screech sodomizing a Jessie/Lisa tag-team as a self-gratifying Zach cheers them on.
