Martin took calls from viewers about their problems, but was left baffled after Phillip Schofield interrupted and suggested he had used a swear word.
Some Twitter users claimed the offensive term he used was “sh**es”, while others said “shyster” may be the problem.
Martin seemingly slipped up and said “sh**es” instead of sites.
He went on to say some of them are “outrageous” and “that’s why I call them shysters”.
“That’s not a swear word by the way, so we’re fine,” he added.
As he continued to speak, presenter Phil muttered: “What you said before was though.”
“What was that?” Martin asked, baffled.
“Don’t worry, roll it back,” the host replied, wanting to swiftly move on.
