Mel Gibson reveals story about Muhammad Ali on Joe Rogan's podcast that he 'doesn't know if he's allowed to tell'

Mel Gibson has revealed a story about boxing legend Muhammad Ali that he 'doesn't know if he's allowed to tell' during an episode of Joe Rogan's podcast.

The American actor and filmmaker was appearing on the latest edition of 'The Joe Rogan Experience', which aired this week.

While the podcast was filmed, Gibson's house was burned down as a result of the wildfires that are raging through Los Angeles, California - with the 65-year-old revealing to reporters that he was 'kind of ill at ease while we were talking, because I knew my neighbourhood was on fire ... I wondered if my place is still there'.

During the podcast itself, Rogan and Gibson moved on to the UFC - a sport Gibson says he is 'addicted' to - with Rogan noting how he can recognise when some fighters' speech patterns are beginning to slur towards the end of their career, due to previous damage taken.

Gibson then brought up Ali, who suffered from Parkinson's disease from 1981 up until his death from a respiratory illness in 2016. The causes of Ali's disease were never determined - doctors do not know why people developed Parkinson's - although there was speculation that it was caused by repeated blows to the head while boxing.

He said: "I met Muhammad Ali when he was in a chair. And I don't know if I can even tell this story - what he said was so funny.

"But he was still in there, he was still a little devil. He was still f***ing with people.

"I can't... I can't tell you. No, man. But it was my assistant, what he said to my assistant, it was so funny.

"He said it, and we all went like, 'Woah!' And I looked at him, and he was laughing his a** off. So he was still all in there, but I guess he had the damage from the punching. It's not good."
