Are you even surprised?
James Corden and his team on 'The Late Late Show' came up with the 'Dame Judi Dench Challenge' while they were filming their series of special London shows earlier this year so it was only natural that when Dench herself paid a visit to the show that she try it out for herself.
Turns out, she's a master at it but considering it's her name, she's probably had a lot of practice. Kyle MacLachlan doesn't really make for strong competition though.
