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."
How awesome if he joined!
