Eddie McGuire revealed the time he suspected a contestant of cheating on Who Wants To Be A Millionaire? and had security search the man for a wire.

He shared the incident during an interview with Kyle and Jackie O on KIIS FM this morning.

“I thought … absolutely something was wrong,” the game show host said.

The contestant was the second person to win the million dollars on the Australian show, Martin Flood.

“He just had this peculiar way of answering a question,” McGuire said. “He was going all over the place.”

“We actually checked him to see if he had a wire on because we thought maybe he had somebody outside and he had a phone attached to his calf. It was just so odd what was going on.”

Turns out Mr Flood was just nervous because he wanted to win.

“He was fantastic and he’d relaxed,” the host said. “What we found out is that he (Mr Flood) took a year off work to study every question he could get his hands on from around the world. He also studied me for any ticks or any gives that I was giving.”

Mr Flood agreed and shared the incident to the Sydney Morning Herald to explain how intense he was.

“I watched every episode of every quiz show I could, I read many trivia books and I went to many trivia nights.

“I could hardly chat with anyone without trying to turn the conversation to last week’s episode,” he said.
