First and foremost I want to warn you that there is some foul language in the video. I would not recommend watching around kids or in the workplace unless you mute it.
With that out of the way, this is what went down. Tony Stewart took part in a sprint car race in Jackson, Minnesota the other night. Unfortunately his engine blew just one lap into it, so clearly the fans were disappointed.
Afterwards he was signing autographs, and some idiot in the crowd started yelling at him for QUITTING the race. There's cell phone footage, and you can see him trying to ignore the guy. But then they start giving each other the finger, and then it is on!
Tony ran straight at the guy . . . threw a left hook . . . and LANDED it. According to police, no charges have been filed . . . at least not yet. According to sources it was "handled internally by race track officials."
