The magician, who claims to have been inspired by Uri Geller, admitted it is technique, confidence and “bulls**t”.
After gasping, Susanna interrupted: “And one of those words we can’t say at that time in the morning…”
Lior apologised himself, explaining he isn’t from the country.
What’s more, the mentalist went on to read Piers Morgan’s mind and the result left him horrified.
Through various techniques, Lior slowly managed to work out the illusive pin code of the outspoken presenter’s bank account.
After he wrote the figures “three” and “five” on a piece of paper, Piers grew worried.
Lior then concealed the notebook from the prying eyes of ITV viewers and proceeded to guess the remaining two numbers.
Piers was completely gobsmacked and insisted: “I’m not even looking at you!
“How do you know?” he demanded to know.
Meanwhile, viewers were loving the magician’s tricks and flocked to Twitter to praise him.
One wrote: “How brilliant was @LiorSuchard on #gmb bravo! Blew. My. Mind.”
A second added: “Watching mind reader mentalist Lior Suchard on #GMB and it’s given me goosebumps! This guy is amazing!”
A third posted: “This is crazy!”
Another laughed: “Live scenes of @piersmorgan leaving the #GMB studio, in the direction of the nearest ATM with PIN facilities…”
