The squeaky-voiced 34-year-old took to the stage on Saturday and won the latest golden buzzer of the series.
Matt - who described his style of magic as "a little bit crazy, a little bit variety" - kicked off his performance by explaining: "I'm gonna give this a big build up in the hope that everyone claps really loudly, and all the ladies take off their bras and throw them in my face.
"Looking at you, Alesha [Dixon]!"
"What a brilliant way to present a magic trick," reviewed David Walliams. "I love when people push jokes as far as they can possibly go. It was very funny, very entertaining."
Simon Cowell added: "When you started with that voice, I thought, 'this is gonna be really annoying'. Actually, you are brilliant. I'm surprised you haven't had a break yet, you're really likeable and nuts."
But the judges weren't the only people left in stitches by Matt's act - and just as they began to vote, Ant and Dec emerged from the sidelines and hit the Golden Buzzer, guaranteeing him a place in the live shows.
With Ant and Dec's golden buzzer, Matt is straight through to the live finals where he could potentially end up performing for the Royal family at this year's Royal Variety Performance.
And if Matt does get to that point, he's got big plans.
"I’d love to cut the Queen in half. I think she’d love it. But I don’t know if they’d let me do that!” he told the Daily Mirror newspaper.
Speaking to the tabloid, Matt went on to reveal how he auditioned for BGT after being inspired by last year's winner and fellow magician Richard Jones.
“I’ve seen what it’s done for his career so I thought I’d give it a go,” said Matt.
Other acts on this weekend included real life couple Tyrone & Mina who like to do “dangerous things” together, with the pair bringing a shocking knife throwing act to the BGT stage.
We also met singer Jamie Lee Harrison, dance group TNG and tappers TapTastik.
Britain's Got Talent 2017 continues Saturday nights on ITV with More Talent on ITV2 straight after.
