Tulkinghorn well knows that barristers like to talk a lot. He supposes that the letters QC should stand for "quite chatty". But even Tulkinghorn was unaware that Blackstone Chambers silk John Howell QC's part-time job across the pond involved a lot of talking.
It seems the garrulous lawyer has been supplementing his income filling in as a body double for David Letterman, the quite chatty host of The Late Show with David Letterman.
Howell has managed to capture the smile of Letterman and even had a pair of replica glasses made especially for the occasion.
