VIDEO: Billy Crystal and James Corden are 'Faking It' on THE LATE LATE SHOW

Ahead of his appearance on The Late Late Show couch, Billy Crystal and James Corden sit down for lunch and launch into a very familiar dialogue about faking it. In the "When HARRY Met Sally" parody, the two debate whether a late night host has faked a laugh when Billy is on the show. And Jay Leno will have what James is having.

Each weeknight, James Corden invites the audience to join in on the fun as the Emmy Award-winning THE LATE LATE SHOW WITH JAMES CORDEN features a mix of celebrity guests, musical acts, games and sketches. Corden differentiates his show by giving a peek behind-the-scenes into the green room, bringing all of his guests out at once and lending his musical and acting talents to various sketches.

Additionally, bandleader Reggie Watts and the house band provide Corden with original, improvised music throughout the show. Since Corden took the reins as host in March 2015, the show has quickly become known for generating buzzworthy viral videos, such as "Carpool Karaoke."
