Veteran funnyman Adam Sandler was on Jimmy Fallon'sshow this week talking about his new film 'Pixels' when he expressed an interest in interviewing himself.
Obviously that's not entirely possible, but with the wonders of modern technology, Fallon gave him the next best thing - a Lip Flip.
The result was a hilarious exchange between the two, with Jimmy's over-the-top impression of Sandler culminating in the pair singing a duet in each other's voices.
