It’s like a car crash – you don’t want to watch it but you just can’t help but stare in fascinated horror. Diamond – AKA Screech  from 1990s kids’ show Saved By The Bell – tried to save a failed career by releasing the tape of himself sleeping with two wannabe porn stars in 2007. It’s pretty vile. He later said that he used a dick double – seriously? – and regretted releasing the film. Not surprising, given that he is now known as the guy that made the ‘Dirty Sanchez’ famous. Ew.
