A man claims to have a sex tape that features Screech.

Notorious celebrity smut broker David Hans Schmidt told the New York Daily News he has a sordid tape that he claims stars Dustin Diamond, who played the nerdy-but-lovable Screech.

According to tmz.com, Diamond didn't confirm the existence of the tape but told a Tampa radio station: "It's very possible that tape exists. ... I've had a lot of fun with video in the past."
