Phillip Schofield was left open-mouthed and red-faced after the man with the 'world's largest penis' showed it to him on live TV. Watch below:
As you'd expect, when presented with photographic evidence of the actor's 13.5inch penis, the pair couldn't contain themselves.
During the interview, Jonah had been using a number of objects to give them an idea of what he's carrying between his legs all day, comparing his penis to a Pringles tube and a girthy aubergine.
But nothing really compares to the real thing, does it? So he decided to give them a proper visual.
"Oh, fire!" gasps Phil, while and embarrassed Josie turns her head away.
Jonah then tells them: "So now you no longer have to compare to these objects."
To which Phil says: "Congratulations."
Jonah has spoken previously about his massive penis, opening top about some of the difficulties it has brought to his life.
The New York-based actor said casting directors will Google his name, find out what he's famous for and decide against offering him the role.
He told the Sun: "It's handicapped my acting because people won't hire me.
"They Google 'Jonah Falcon' and then say, 'We can't use him he's known for his penis size'.
"It's definitely harmed my career - I have two casting director friends who have told me so."
He was also left red-faced when he was searched for possible explosive while travelling through a US airport.
Officials at San Francisco Airport feared Jonah may have been a 'biological threat' after they spotted his 'noticeable' bulge... we'll leave that one there, eh?
Jonah says he gets 'lightheaded' when he gets an erection, but despite this, he does say he 'wouldn't change anything' about his willy.
But it's not just Jonah who struggles with his old fella - Roberto Esquivel Cabrera, who is the owner of an 18.9inch willy, claims that his member has also held him back.
Roberto, who lives in Mexico, says he has had to register himself as disabled and now relies on food banks.
He explained in an interview: "I cannot wear a uniform like anybody in the companies and also I cannot get on my knees.
"I cannot run fast and so the companies think badly of me. They say that they will call me, but they never do."
He also said that his penis stops him from having sex, adding: "I can never penetrate anyone because it is too thick."
