Charlie Zelenoff, a well-known “internet troll” who proclaimed himself the greatest boxer in history with a fictional record of hundreds of victories, showed up at the Mayweathers’ gym in 2011. After verbally harassing Floyd Mayweather Sr. (who at that time was nearly 60 years old), a sparring session was arranged.
Despite the huge age difference, Mayweather Sr.’s technical experience dominated Zelenoff. The most infamous moment occurred when, after being physically outmatched, Zelenoff tried to attack the veteran from behind while he was resting on the ropes. This prompted the immediate intervention of the gym members, who ended up violently removing Zelenoff from the ring.
The incident became one of the most viral videos of its time, highlighting the danger of confusing internet confidence with the reality of professional sports.
