A topless showdown with Mike Tyson, destroying a stage, headbutting a glass wall – and lashing out at KSI: the bizarre pre-fight antics of Tyson Fury’s hellion dad John – as stunned fans brand him ‘the most embarrassing man alive world’ ‘

Tyson Fury’s creepy dad John was today branded ‘the most embarrassing man alive’ after the latest in a series of bizarre outbursts at his sons’ pre-fight press conferences.

In recent months, the 59-year-old has been seen headbutting a glass wall, destroying a stage and being restrained by security while making a ‘cringe’ call from heavyweight boxing legend Mike Tyson.

John, a former professional boxer himself, was last seen on Thursday storming off a stage towards Iron Mike and shouting: ‘You want to fight me? I can fight you now before I’m stopped by guards.

As his son Tyson posed for a staring photo with former UFC heavyweight champion Francis Ngannou – who he fights tomorrow night in Saudi Arabia – a shirtless John tried to walk in before being led away by a nanny.

In response, Twitter user Jake Best wrote: “John Fury is by far the most cringeworthy person on the planet.” A second wrote: ‘Hearing John Fury shouting ‘I fear no man’ has become incredibly boring. Nobody cares, dude.”

John had been heavily involved in the build-up to the fight, having ensured that the first press conference in August came to an abrupt end when he smashed and turned tables on stage.

John went on to say, “The Furys dominate. We are the best men in the world. We will fight anyone who comes our way.”

John said: ‘Full of s***. Filled with ***. Shut up, mother***. Now come fight me instead of talking all that shit about people’s damn assholes.

‘We’re fighting men. My son (pointing to Tommy) will now fight him (pointing to KSI) and then fight anyone else who wants it. Now let’s get the ball rolling.

“Take the pie and shove it in your hole before I do.” All these little damn kids. I am a machine. Me! Can anyone wonder who I am here? I’ll take them’.
