HOLDING three numbers in your head doesn't seem like much of a challenge, right?
Guess again when Coffs Coast mentalist Johnny Sublime's doing the asking.
Ahead of his audition for Australia's Got Talent at Opal Cove Resort on Tuesday, Johnny dropped in to the Advocate and gave a demonstration.
"The thing with mentalism is people assume it's about psychic ability, but when you're reading someone's mind it's more about planting thoughts there," Johnny said.
For his demonstration, Johnny asked for a signature on a card next to three numbers before the card was held in the subject's hand.
He then set about giving a seemingly random explanation of how most people suffer from some form of amnesia in their lifetime.
By the end of it, the subject is convinced they still remember the three-digit number on the card.
Only to find a completely different number on the card, complete with signature.
Johnny said learning the art was a combination of observing other mentalists and figuring out how techniques were done, as well as a stint being mentored by Singapore magician and mentalist Yuleo.
"I started out watching UK mentalist Derrin Brown. He never reveals his secrets, so I had to work out what he was doing and reverse-engineer a method to make it work with my own twist," he said.
"You're never sure. I could have done something a thousand times and it could still go wrong."
Australia's Got Talent has had a large number of Coffs Coast residents apply so far, with the majority performing music, but casting staff are ever on the lookout for the quirky and different.
