Viewers of The Late Show were left stunned as Prince Harry opened up on a personal cushion that could have helped him avoid a delicate situation.
Continuing his publicity tour for his new memoir titled Spare, the Duke of Sussex, 38, downed tequila while chatting to US presenter Stephen Colbert.
And the audience stateside lapped up the appearance, learning new words along the way.
As Stephen quizzed the prince on specific sections of his book, he turned his attention to a passage which detailed Harry getting frostbite on his penis.
Telling Stephen to open up on the events, Harry labelled his manhood his "todger," much to the amusement of the host, who called it a "very gentle word".
After a funny back and forth surrounding the word, Stephen asked his guest how he managed to get frostnip on his North Pole escapade.
Harry said: "It's really hard to have this conversation because there's no one in this audience that has probably read the book yet apart from you and me."
Stephen fills in the audience explaining how Harry had gone to the North Pole and "things got very cold". He then asked: "At what point did you realise there was a crisis at the 'South Pole'?"
"Once I got home," Harry revealed. "The problem was – firstly, it didn't turn into icicle," he explained before saying thankfully he is fine now.
He continued: "The context was these amazing veterans were doing a walk to the North Pole. They had all the training – I had none. And I turned up thinking 'how bad can this be?'"
Making light of the situation he said: "It's only the North Pole. It's only minus 35 degrees," before adding: "I've got the salopettes, I've got the jacket, I've got the warm stuff. I've got all of the things that I need.
"But what I didn't have was what I had when I actually went to the South Pole which was a c*** cushion."
Despite Harry staying straight faced, Stephen couldn't help but burst into laughter – something which was echoed by the audience and a number of people in online comments.
One user on Twitter wrote: "Hearing Prince Harry say c*** cushion was probably the most unexpected moment of my life."
Another gushed over the prince and said: "C*** cushion! Lmfaaaaaoooo. Prince Harry is the best.@colbertlateshow".
A third added: "I wonder how long it will take for #c***cushion to start trending. Well done, Prince Harry!," followed by a crying with laughter emoji, while a fourth joked: "Learned two words today: “c*** cushion” - would’ve protected him from his “todger” getting frost-nip. #Spare".
