The first Saved by the Bell vet to star in a sex tape ? Showgirls excluded ? is neither cutie "Zach" nor beefy "Slater," but Dustin "Screech" Diamond. According to the New York Daily News, the now 29-year-old actor/punch line engages in a kinky three-way with two women in a 40-minute vid tentatively titled (avert your eyes now) "Saved by the Smell" and being shopped around by celebrity-skin kingpin David Hans Schmidt. Diamond's manager, who has yet to see the actual tape, tells the News, "He has been trying to escape the Screech typecast, so this may help me get more bookings." Sure, but on what?
