Lifetime has released a sneak preview of its upcoming "The Unauthorized Saved by the Bell Story", and if you were or are a fan of the show, prepare to be disillusioned! 

There's plenty of infighting among the cast, including catfights between the female castmembers over Mark-Paul Gosselaar (Zack Morris), plus we find out that Dustin Diamond (Screech) was really bad at push-ups.

The movie is scheduled to air on Lifetime Monday Sept. 1 at 7 p.m. (CT) Watch the footage and get ready for your childhood to be ruined!
