Sally is joined by writer, actor and sketch show royalty, Paul Whitehouse. In this episode Paul chooses the comedy sketches that took him from the Valleys in Wales, to the big screen, via The Fast Show. His personal selection is a joyous mix of Python, Alan Partridge, Victoria Wood and his old pal Harry Enfield. Paul reveals the inspiration behind "suits you sir", his chance meeting with Fry and Laurie, and why one of his selections is the "perfect sketch". All this is topped off at the end with a re-enactment of his favourite sketch.

Star of W1A and Spaced, Jessica reveals her eclectic mix of favourite sketches with the finest works of French & Saunders, Mitchell & Webb, Catherine Tate and Big Train. The highlight is the re-make of Jessica's favourite sketch.

Stand-up comic, Jason, reveals his playlist of the sketches that followed him from childhood to the present day. His selection is a mixture of high and low brow, with Les Dawson and Hale and Pace rubbing shoulders with Key and Peele, Steve Coogan and Caroline Aherne. Ending the show in style, Sally and Jason take on his favourite sketch, an American cult-classic.

And not forgetting Johnny's tribute re-enactment of his favourite sketch to close the show.
