When Ricky Gervais was presented with the opportunity to interview himself, how was he ever going to turn it down? Next thing we know, Gervais is resembling a rosy lipped, albeit scruffy, cherub. Fallon, meanwhile, morphs into something resembling a stoned catfish. That's probably not the best description, but there's just very few ways of describing the marriage of Jimmy Fallon's face and Ricky Gervais' MENTAL vampire teef.
Be warned, both characters sound like Herbert off Family Guy. There's even a ball shaving reference.
