Jonah Falcon was on the ITV show to discuss life with his huge manhood, which he says measures 13.5in, and as Schofield and his co-host Josie Gibson tried to work out how big that was he offered to show them a photo.
He then whipped out his phone and presented it to Schofield, whose jaw dropped.
“Hellfire!” he exclaimed when he saw the picture, while Gibson – who is filling in for ill Holly Willoughby – looked equally gobsmacked.
