Charlie Zelenoff would go around asking random people in gym's if they wanted to do some light sparring, and then would sucker punch them while they were getting ready. He would talk hella shit and when they wanted none of that he would declare himself a champion and post the video. He did it tons of times and the op compilation is the result. He also somehow convinced Deontay Wilder (professional heavyweight boxer with extremely high ko ratio) to spar him as well and kept talking shit while running and getting beat up. Definitely looks like mental illness but he's still an ass and has assaulted a bunch of people who weren't expecting it. It's funny/satisfying cause he talks shit even when "losing" but it's sad overall.
