This Morning presenter Holly Willoughby and co-host Phillip Schofield kept their composure on Thursday as they probed a guest who is thought to be the world's most well-endowed man.
Schofield - who was celebrating 10 years on the show - and co-host Willoughby spoke to New Yorker Jonah Falcon about his life with a record-breaking penis.
Falcon, 41, recently caused a security alert at a US airport due to the bulge in his trousers.
He told the ITV1 presenters: "When I look down at myself I don't see anything special. But I still enjoy having something special - every person does."
Falcon, who has struggled with relationships, said he would not change anything about his unusual size.
"I feel like I'm fine the way I am," he said.
Falcon said he first realised he was different at the age of around 10, when his schoolmates used to talk about him although he assumed it was because he had not been circumcised while his friends had.
"I was eight inches at the time. Now it's around nine - and 13-and-a-half when erect."
He said he had been offered porn work but had declined it: "I can't perform in public - I'm a show off, but not doing it in front of other people."
Falcon told the presenters he used to wear tight cycling shorts and wrap his penis around the side of his leg.
Schofield told viewers wistfully: "Ah, it's a clever trick if you can do it."
ITV said it had received no complaints about the subject of the interview, and nor had media regulator Ofcom.
Explaining the reason for having him on, Schofield said: "We've had the lady with the biggest breasts in the world and so we thought it was about time we redressed the balance."
