Although they may have been legends in their prime, sometimes, former athletes can end up missing the limelight and do some pretty strange things to try and stay current and relevant in modern society. This former pro boxer in the red helmet seems to be one such athlete. He decided he wanted to put on a show for passersby in the street and challenged them to try to touch him. All he has to do is dodge their advances.

The ex-boxer refused at first, then agreed to hit back, but only with his left hand. But when his opponent decided to go harder, the boxer decided to follow suit.
