John Fury heard all of the verbal jabs being exchanged between his son Tommy Fury and KSI at their Tuesday press conference in London to build toward their October 14 fight, live on DAZN.
He sat patiently listening to it all as the insults grew more heated ... until he had enough and exploded.
"F—k all this s—t!" the dad of WBC heavyweight champion Tyson Fury and Tommy Fury suddenly got up and yelled.
Fury expressed more disgust for all the fighters on the dais — Fury, KSI, Logan Paul and Dillon Danis — who took personal shots at each other in his presence.
"How can anybody question who I am here?" he asked.
At that moment, the Fury father slammed his fist on the press conference table, slapped the microphone off of it and flipped over the table, altogether.
He then walked over to the other table and kicked it off the stage, too, prompting KSI to rise up out of his seat in attempt to confront the Fury side, before both parties had to be separated by security.
Just like that, John Fury destroyed the press conference in a memorable moment toward what's bound to be a wild fight between his son and KSI in just over two months.
The destruction of the press conference delayed the session until it later resumed without any furniture on stage.
