Videos showed three-time NASCAR Sprint Cup champion Tony Stewart confronting a heckler in the stands of Friday night's Chili Bowl dirt-track races in Tulsa, Oklahoma.

Multiple witnesses said the fan flipped Stewart off before the confrontation.

Video posted by Tyler Haire on Facebook shows the heckler yelling, "I don't like ya, I never have!" while Stewart calls the man an obscene word.

More than 700,000 people have watched it since it was uploaded last night. (Update: The Facebook post was taken down, so we have embedded a YouTube mirror of the video.)

Security shoved the man into his seat while Stewart continued to get in his face.

Stewart was involved in the fatal August 2014 accident that killed rival driver Kevin Ward Jr. and has a history of having a short temper.
