Britain's Got Talent fans will witness an excited David Walliams drop his trousers in Simon Cowell's face on Saturday night's show as the judges prepare to narrow down this year's crop of contestants.
In the final round of auditions, viewers will see 68-year-old Audley Buckle from Huddersfield orchestrate a crowd sing-a-long with his catchy tune Chicken And Chips.
Even Cowell managed to mouth the song's finger lickin' good chorus as Buckle, a former Bob Marley backing singer, bounces around the stage alongside Ant and Dec, who munch on some chicken and chips.
Buckle's audition comes as the judges face the difficult task of cutting down this year's group of talented contestants to those who will get a chance to perform in the live semi-finals alongside the five golden buzzer acts.
The final audition of this year is singer Sue Moretta from Clayton Le Moors in Lancashire, whose rendition of Don't Rain On My Parade prompts David Walliams to drop his trousers in Cowell's face.
A traumatised Cowell struggles to regain his composure as he admits "I literally can't get this thought out of my mind, what I just saw."
Also on Saturday night's show is an alphabet spaghetti-influenced magician, a pair of Irish brothers dancing to A-Ha and a street group dance made up of 17 young performers from across the globe.
Lords Of Strut, a pair of Irish brothers from Cork, perform a tongue-in-cheek 80-dance routine to Take On Me and receive a standing ovation from the crowd in Manchester.
Empire Dance Crew perform a routine to a medley of Little Mix tracks while magician Neil Henry, 38, draws Alesha Dixon on stage to assist him with a trick which involves spelling a word with alphabet spaghetti.
An all-female dance crew made up of teenage best friends Claudia, Tag and Maria perform a routine to a pop medley, while Irishman David Geaney, 22, combines his passions of dance and technology to try to impress the judges.
All the acts who have received qualified throughout the past seven weeks of auditions then face a nervy wait as Cowell, Walliams, Dixon and Amanda Holden decide who will reach the coveted spot in the live shows.
