The five celebrities are thrown in at the deep end as their mentors put them straight on stage to gauge their sense of natural comedic talent - in some cases, very little! Former Coronation Street actress Katie McGlynn struggles without a script to hand, reality star and dancer Curtis Pritchard teeters on the edge of a very cringey overperformance and 90s music legend Shaun Ryder, who has ADHD, has a complete mind blank and immediately forgets the stories he wants to tell the audience.

Reverend Richard Coles's mentor David Baddiel was hoping for something more original and unexpected and Baroness Sayeeda Warsi's left-leaning tutor Nick Helm cannot believe his task is to make a Tory look good.

With just fifteen days to perfect their act, Shaun and Sayeeda go back to their roots to gather material, Katie rushes to write herself a script to help overcome her nerves, Curtis is drilled in dropping the jazz hands and David attempts to push Rev Richard into darker material, suggesting he draw on his grief following the death of his partner.

Jason Manford appears to have the biggest mountain of all to climb with Shaun Ryder to coach. Despite Shaun displaying an extraordinary degree of confidence, he tells his mentor he has nothing to worry about and will just be able to wing it on the night.

Throw in an attempt to persuade a Vicar to add some swear words to his set, a Baroness in fancy dress and some excruciating practice performances and its little wonder both the celebrities - and their mentors - wonder if they've taken on too big a challenge.
