Mike Tyson burst into a hysterical laughing fit while recording a boxing promo – after hearing that KSI said he would beat him in the ring.
Iron Mike is back in business at age 54 as he prepares for a comeback fight against Roy Jones Jr in November.
But the self-styled ‘Baddest Man on the planet’ was in tears as he laughed uncontrollably for three or four minutes straight in a hilarious video posted on Twitter.
Tyson’s giggling fit came after KSI boasted in the latest Sidemen video that he could beat the former undisputed heavyweight champion.
The hugely popular YouTuber even claimed that Logan Paul – the man he defeated in his first pro bout last year – would also get the better of Tyson.
Asked whether he could beat Tyson, KSI said: “I actually could though, I actually could.
“I’m undefeated, no-one has beaten me.”
KSI was then jokingly asked if he thought Tyson would draw with Paul – as he himself did in the first contest between the YouTubers in 2018.
He replied: “I think Logan would beat Mike Tyson.”
Asked why he thought he would win against the man who became the youngest ever heavyweight champion at 20 years old, KSI said: “The reason why – age is on my side. Age is on my side.
“In the first few rounds I ain’t going [all out].”
No wonder Tyson was in hysterics – although it is not clear whether this was actually what he was laughing at in the video posted by BT Sport.
Meanwhile, KSI later clarified his comments, making it clear he was joking in the Sidemen video.
The 27-year-old tweeted: “Gonna kill this real quick. I don’t want to fight Mike Tyson. The man is a legend. You got trolled from a drunk sidemen video.”
Tyson has shared training videos showing he still has his devastating speed and power as he prepares to fight 51-year-old Jones in an exhibition bout on November 28.
It will be his first return to the ring since 2005, when he was stopped by Kevin McBride.
