Led by Alexander Armstrong and Ashley Banjo, the group performed a striptease to nearly 3,000 people at the London Palladium, all broadcast on ITV.
In the hope of raising awareness of testicular and prostate cancer, the duo alongside Matthew Wolfenden, Wayne Sleep, McFly’s Harry Judd, Mark Foster, TOWIE’s Elliot Wright and Dom Littlewood all got their kit off after just six rehearsals.
Twitter was inundated with comments about their efforts, claiming it was hilarious while applauding them for being so brave.
After Death in Paradise star Danny John-Jules was forced to pull out due to “filming commitments”, Diversity favourite and choreographer Ashley stepped in – thanks to much encouragement from his co-stars.
Many at home couldn’t believe they stripped down to their birthday suits, leaving many amused with their antics in training.
Two tweets read: “Crying with laughter and pride at #TheRealFullMonty, well done fellas,” and: “@AshleyBanjo AMAZING! U had me crying and cheering! So, so proud of u all #TheRealFullMonty.”(sic)
A third user wrote: “Haven’t belly laughed like this for ages! Hilarious! Well done lads! You’ve got a lot of balls! Pardon the pun! #TheRealFullMonty.”
Another agreed: “Just cried at #TheRealFullMonty… not at the sight of the willies! Just such a bl**dy wonderful cause… oh and I probably need more sleep.”
As well as some saying it was there “favourite programme of the year”, others commended their efforts in the hope of convincing men to check themselves.
“This is absolutely brilliant #TheRealFullMonty @ITV Raising awareness for such a good cause in such a fun way. Good job @AshleyBanjo,” one person wrote.
