The British comedian says he had an outrageous opening planned for his latest gig hosting the prestigious awards ceremony - as a wild jab at Mel Gibson.
But when he told Golden Globes organisers his plan, he was immediately banned from doing it.
'I was going to come out dressed as Adolf Hitler,' he told talk show host Conan O'Brien, showing him that he would throw in a 'sieg heil' salute, too.
'I was going to get to the podium, let it die down - then go, 'Too much?' 'Then I wanted to look in the crowd and go, 'It's the wrong crowd, just the wrong crowd'.
'And then I was going to say, 'That's the last time I borrow a suit from Mel Gibson'.
'That would've been good, wouldn't it?' he asked O'Brien, adding: 'I think maybe they were just worried about the picture the next day in the papers.
'They told me, 'We can't do that' - so I'm not telling them anything more.'
