Over a series of rounds, the two teams of two present Harry with fun stuff which Harry must adjudicate on and ultimately decide what's in and what's out of the Fun Capsule with the triumphant team winning bragging rights.

Along the way there will be sketches, studio items and special guests. And the occasional appearance of an alien.

Harry is joined by guests Kathy Burke, Lorraine Kelly, Ainsley Harriott and Joe Lycett.

Helping Harry this week are comedians Mel Giedroyc and Bridget Christie, and broadcasting legends Eamonn Holmes and Judith Chalmers.

Helping Harry Hill fill the fun capsule and prevent an alien invasion this time are comedians Ross Noble and David O'Doherty, Game of Thrones star Raleigh Ritchie and national treasure Gloria Hunniford.

Helping Harry fill his capsule with hilarious moments this time are Cold Feet star Fay Ripley, former EastEnders actor Nina Wadia, comedian Nish Kumar and showbiz legend Des O'Connor.

In this final episode Harry Hill shares some of the funniest moments that didn't make it into the previous episodes of the series. Expect previously unseen highlights from Kathy Burke, Joe Lycett and Josh Widdicombe as well as others.
