TMZ obtained footage of a man approaching Mike Tyson on a rooftop bar in Hollywood during a small comedy show.

Witnesses say the man approached Tyson in the middle of the comedy show and challenged the famed boxer to a fight, as the man stated that he wanted to elevate his status. Mike kept his cool throughout the encounter, letting the man speak, and the host of the comedy show told the guy to get out. The man then pulled out a gun and threatened to shoot the host, which left people at the show taking cover. The man appeared to regret pulling out the gun, and he asked Tyson not to call the police. Mike seemed unphased, and he actually hugged the guy,
