Andre Berto -- I Had Best Seat in House for Street Brawl!!!

Andre Berto knows how to watch a street brawl ... from the comfort of his Rolls Royce.

The guy who knows a thing or 2 about fighting was out and about Friday night -- on the hunt for toilet paper and Starburst -- when he rolled up on a pack of amateurs throwing punches.

He captioned the video, "This why I stay in the house mane.. Folks out here having Royal rumbles outside like they got W.W.E. Contracts smh..... Man Iam coo."
