Donald Sterling -- Super Racist Comments About Celebs Alleged in Super Ridiculous Court Filing

Donald Sterling made racist comments about everyone from Beyonce to Charles Barkley ... if you believe an ex-Clippers "janitor" who filed for a restraining order against Sterling -- except no one in their right mind would believe this guy.

TMZ obtained a copy of the court doc filed Friday by a Cliff Paul (yes, like the State Farm commercial) who claims he is ... related to Chris Paul, a former janitor for Sterling, and was technically savvy enough to bug Sterling's office for years. You get the picture ... this sounds like a crazy person.

In the doc, he claims to have heard Sterling have hyper-racist convos about Beyonce, Chris Paul, Shaquille O'Neal, and Kim Kardashian -- and most of the language alleged in the document is far too racist to even repeat.

Some tame examples -- Sterling allegedly said Charles Barkley's head looks like a "retread tire" ... and when George Zimmerman was acquitted, he allegedly said ... "Buy that guy a beer." According to the docs Sterling even went to an IHOP with Paula Deen just to laugh at Black dishwashers.

Not shockingly ... the absurd request for a restraining order was quickly denied in a Florida District Court.

No word if this will affect Cliff's contract with State Farm.
