Screech Sex Tape Preview

TMZ has obtained portions of the latest celebrity sex tape, featuring former "Saved by the Bell" star Dustin Diamond, who played Screech. To say the least, the video is unique and, dare we say, entertaining.

David Hans Schmidt, who has become famous in the sex tape industry by peddling videos featuring Paris Hilton, Colin Farrell and others, claims ownership to the Screech tape. It was shot in a hotel. Diamond is holding the camera and narrating, as he engages two women in various combinations and positions.

The tape begins with Diamond in a bathtub, narrating what's to come. It ends with Diamond introducing one of the women to a "Dirty Sanchez." Suffice it say, it is unbelievably graphic.

Schmidt is out shopping the tape and we're told it has been generating significant interest. What's unusual, we're told, is that some mainstream media companies are interesting in purchasing the rights.
