Their frank comments came right at the end of an interview with inspirational mouth painter Henry Fraser, aired on Wednesday’s ITV show.
Henry draws using his mouth – after an accident years ago left him paralysed from the neck down – and now West End theatre show The Little Big Things details his memoir.
After an extensive chat about Henry and his positive attitude – which spurned from his accident – Good Morning Britain fans thought Richard, 67, had put his foot in it.
Earlier in the discussion, he had confessed to meeting Henry before.
And as he wrapped up the interview, he said: “I think you are an extraordinary human being and I am proud to know you,” before jokingly adding: “Can I have a free painting please?”
Susanna let out a laugh at his question and, after giving a giggle, Henry quipped: “We’ll talk, we’ll talk.”
Yet those at home weren’t tickled by the banter.
One took to X, formerly known as Twitter, to post: “What a question… not necessary.”
Another simply put: “Cringe,” as a third commented: “Madeley somehow manages to outdo himself with every interview he does.”
A fan then wrote: “‘Can I have a free painting?’ Madeley you fucking grifter!!”
One then referred to comedy character Alan Partridge and put: “Madeley off the Partridge scale this morning.”
Another surmised: “‘Can I have a free painting?’ The priceless Madeley.”
A GMB fan then concluded: “Henry Fraser, God Love Him, turning his paralysis into a total triumph and a love of art. Genius.”
In 2009, at 17-years-old, keen rugby player Henry was on holiday with his friends in Portugal to celebrate the end of his AS results.
Running into the sea, he hit his head on the sea bed, dislocating the fourth vertebrae in his neck.
After spending three weeks in a Portuguese hospital, he was then transferred to one in England, where he stayed for six months.
However, he was left paralysed from the neck down, and learnt that he had to spend the rest of his life in a wheelchair.
The inspirational artist began by using a stylus on his iPad, which he held using his mouth to draw.
He then taught himself to use a pencil, and then paint, by fixing the utensils required a stick attached to his mouth.
