Internet trolls are the worst.

They hide behind keyboards, saying insulting and hurtful things towards people who are, in many cases, complete strangers.

Charlie Zelenoff is an Internet troll who has been trolling pro boxer Deontay Wilder with insults, racial epithets and more.

Somehow, Zelenoff agreed to take on Wilder in an impromptu boxing match.

The results were perfect.

About three years ago, Zelenoff had a sparring match with Floyd Mayweather Sr., the father of undefeated boxing champion Floyd Mayweather, Jr.
