Billy Connolly has denied Sir Michael Parkinson's claims that his "wonderful brain has dulled" as a result of suffering Parkinson's disease.
The legendary comedian was said to not be able to recognise his friend at an awards dinner the pair attended together - but he reckons that's nonsense.
"I would recognise Parky if he was standing behind me - in a diving suit," Connolly said, according to the Telegraph.
The 75-year-old funnyman's wife was more confrontational in her response - calling Sir Michael a "daft old fart" who "doesn't know what he's talking about".
In the interview with ITV, Sir Michael said the effect of Parkinson's disease on him was "awful".
"To know someone as long as I knew and loved Billy, it was an awful thing to contemplate, that that had been taken from him in a sense," he said on his television show.
Other friends and colleagues of Connolly are surprised by Sir Michael's remarks this weekend and insist he is "fine and well", reports the Telegraph.
