12-year old Thomas Wallis took Britain's Got Talent by storm at the weekend with his VERY unique skill.
The youngster took to the stage in the latest round of auditions to show off his special interest in London's underground tube network.
In an audition cut from Saturday's main show, Thomas introduced himself to the panel before asking them to challenge him.
He explained: "I'm going to give you these underground maps, and you can name any line, and I can name all the stations on it."
And the judges obliged, with Thomas impressing as he reeled off every station on the Central and District lines faster than Ant and Dec could keep up on the sidelines.
The unusual talent got a standing ovation from the judges and crowd.
"Thank you so much," reacted an overwhelmed Thomas.
Asked by Simon Cowell what he'd do in the next round, Thomas revealed: "I'm hoping to break a record for as many stations named in 30 seconds. The record is 73 and I'm going to attempt to break that "
It was then time to vote, with Alesha Dixon kicking off: "I'm so impressed by you, it's a yes from me !"
The other judges followed leaving Thomas with four yeses through to the next round.
Other acts we met this weekend included singing duo The Pensionaires, aka Malcolm and Henry, talented teenager Destiny Chukunyere and David Walliams' golden buzzer act, Kyle Tomlinson.
Plus The sky was the limit for cheerleading squad Coventry Dynamites while we also got to watch auditions from singer Leah Barniville, dance group ALLIN Dance Crew and magician TanBA.
