It's not often you see a dude in a wheelchair in a fist fight. Maybe it's because there's a disparity in mobility between the two that makes things unfair.
One dude thought he'd be able to take down a wheelchair-bound man and found out quickly he was wrong. Wheelchair dude knocks the man to the ground and when he gets back up, he taunts him to punch him in the face. Dude swings and misses and no matter what happens after that, the fight is over.
