MELBOURNE law student Khaled El-Katateny walked away from the game show Millionaire Hot Seat on Monday with $100,000 despite not knowing the answer to a single question.

The 19-year-old had the audience and home viewers in stitches with his comedic antics, which included asking people to follow him on Instagram and telling host Eddie McGuire he planned to buy 10 jetskis if he won.

But instead of relying on his smarts, the second-year university student claimed he used his incredible knack for being able to read body language.

For each of the five questions he was asked, El-Katateny said he repeated the possible answers back and scanned host Eddie McGuire's face for a reaction.

"I didn't play the game — I played the man," he explained.

"If you look at it, you see me working Eddie McGuire. I'm reading every single subtle thing about his face. I was reading the audience behind him too. That's telling me the answer."

The footage doesn't show any readable clues or cues in McGuire's face and the larrikin teenager is looking down at his screen while repeating the options back.

There is every chance El-Katateny, much as he did during his appearance on the show, is simply taking the mickey.

Although the probability of fluking the answer to five questions from four options is low.

Whatever his trick, he has pocketed $100,000 and a couple of hundred new Instagram followers thanks to his on-air promotion of his account.

"When I got in the chair, there were five questions left to $100,000. I thought I'd make the best out of it and yell out my Instagram."

His username, which he reminded viewers repeatedly, is Kahled_ELK. His profile features a collection of selfies, pictures of his car and happy snaps with mates.

While he told McGuire he'd buy 10 jetskis for him and his mates if he won, El-Katateny has since backtracked on the cash splash.

"I'm definitely going to buy one jetski, but not 10. Look, it has struck a bit of controversy (with my mates).

"I really, really need a car charger for my phone. Every time I go somewhere, my phone dies — especially now it's blowing up."

Before planning how he'd spend the money, he offered it all to his parents but they refused the generous gesture and told him they were proud of the remarkable effort.
