JOHN FURY said son Tommy will punch KSI until he "URINATES" himself and warned it will be a "street-fight with gloves on."
The celebrity boxing pair meet in a massive battle of Britain bout on October 14 in Manchester.
Their launch press conference descended into chaos when Fury's dad and coach John began flipping tables on stage.
And the former bare-knuckle boxer predicted more carnage come fight night.
John told Boxing Social: "We are training for an old-fashioned punch up. There is no-rules, it will not be a boxing fight.
"It will be a punch up until one submits. In a Misfits fight anything can happen, Tommy will grab hold of him and punch him until he urinates himself.

"It is our duty to entertain. You can only entertain with blood and snot coming out of each man. This is a street-fight with gloves on.
"We are not going to show nice boxing skills, we will go to club him into submission. Tommy is a strong man. It is about who wants it the most.”
Fury, 24, comes into the fight having beaten KSI's arch rival Jake Paul, 26, via split-decision in Saudi Arabia in February.
But after Paul decided to return in a win over ex-UFC star Nate Diaz, 38, Fury secured a bout against KSI, 30.
