Now, we're not condoning violence but there is something very satisfying about this clip.
Heavyweight champion Deontay Wilder got so fed up with three years of harassment and pestering from Charlie Zelenoff he decided to do something about it.
Wilder described the last straw to TMZ: "He said he was going to murder me. He said he was going to tape my daughter's mouth ... when dealing with my kids, that's below the belt. That's what really got me."
A confrontation - complete with waiver for Zelenoff to sign - was arranged for 7 May.
The result is plain to see - that troll gets gets an absolute hammering, lessened slightly as Wilder accidentally picked up two right-hand gloves.
Despite his clear enthusiasm for teaching Zelenoff a lesson, Wilder claims to have his best interests at heart.
He said: "I genuinely care for the guy. I want him to stop [harassing people] before he messes with the wrong person. You never know who you're dealing with."
