Jimmy Carr is renowned for his close-to-the-bone jokes - but even he realised he had crossed the line when he targeted Professor Stephen Hawking.
The comedian faced backlash recently over a 'sickening and unacceptable' Holocaust 'joke' featured in his Netflix stand-up special 'His Dark Material'.
He admitted he was worried he was 'going to get cancelled' for the derogatory line which made reference to the almost half a million Roma and Sinti people murdered in Nazi death camps.
