Proof positive that the "celebrity sex tape" trend has officially gone too far

Anyone who enjoyed, in any way, certain video curiosities and experiments done by people like Paris Hilton...we owe the world an apology. Because it's led to this. Three words: Screech sex tape.

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."

This is the kind of thing which could lead to the extinction of the human race because no one is going to want to have sex ever again.
