The guys have saved up enough money to go on holiday. They're all set to go until Stef discovers that Ash has changed all of their passport photos for selfies. In light of this, they have to set their sights closer to home and end up camping under a holiday billboard in a local car park. But will the boys survive the week without killing each other? This show has two new songs: Holiday, featuring a sample from Cliff Richard and The Shadows' classic hit Summer Holiday, and When I'm Older, in which the boys imagine what life will be like when they're old and grey... it's not pretty.
