JOHN FURY shocked sons Tommy & Tyson with a vile X rated rant directed at Jake Paul during a prefight press conference.
Jake, from the US joined the Zoom team as Jake joined the presser.
The ocean that separated the two camps didn't stop Tommy's father John from having a terrible exchange with YouTube star.
John responded to Paul when he had interrupted proceedings and said: "Shut down schoolboy, speak when you're spoken to."
"Stop yelling, we're with the big dogs now.
John jumped out of his chair and appeared to be ready to punch Jake.
Tommy's father lost his head when Paul called him a "single-old man".
John said: "You can thank you lucky stars I'm barred from your country cos that I'd get to you and slap your bum."
Paul told John to "suck his d**k", which John replied, "Suck your da**k?" You don't have a d**k...you have a gr**h and not a da**k."
Tyson, a heavyweight champion, was stunned by the comment and covered his face with his hands.
John made the shocking comments after Paul's girlfriend Julia Rose called him a "dog".
He said, "You know Tommy knocks your out, don’t you?" He will make your girlfriend look like a dog and bend over to her. You're going to get what I'm telling the truth.
Tommy and Jake will be meeting in the ring in Florida on December 18, as they prepare for their unbeaten records.
Paul has defeated YouTuber "AnEsonGib", ex-NBA star Nate Robinson (37), and Ben Askren (37).
In August, however, he improved his record to 4-0 by winning eight rounds against Tyron Woodley (ex-UFC champion), 39.
Tommy defeated Anthony Taylor, Paul's sparring partner, on the undercard to make it 7-0. This set up the megafight.
Tommy is training with Tyson, his WBC heavyweight champion as he prepares for next month's grudge match.
