We're not ones to put words in other people's mouths...but it seems that Jimmy Fallon and Ricky Gervais are.
A hilarious new feature on The Tonight Show with Jimmy Fallon saw special guest Ricky Gervais 'flip lips' with the American TV host, as the pair interviewed each other, as each other, with predictably excellent results.
It culminated in a spirited rendition of Bing Crosby and David Bowie's festive classic The Little Drummer Boy, which had previously made our list of Strangest Musical Duets. You'd have to argue that this version probably merits inclusion too.
Watch the whole sketch below.
