Britain's Got Talent 2013 continues this weekend and there's yet more wacky performances.
Entertainers Dueling Pianos are perhaps the most bizarre - and yet still talented - acts the show has ever seen.
The pair, made up of Bill Whitman and Craig Schuster, take piano music and turn it into a competition between themselves.
The duo have taken their act around the world, having previously appeared in the US with their rather wonderful performance.
But while Alesha Dixon, Amanda Holden and David Walliams love the act, Simon Cowell's not to sure.
Little Britain comic David is seen getting up during the audition to encourage the music mogul, forcing him to clap his hands and make Simon smile.
Can Simon keep a straight face or will he give in and send the Dueling Pianos through to the next round?
Even if the piano pair do make it through, they've already got some tough competition to beat to get into the live shows.
There's only been two weeks of BGT auditions, but there's already a big front runner in the form of Attraction.
Jessica Bridge of Ladbrokes said: "After week two of BGT auditions Attraction are looking safe at the top of the market. At this stage only Jordan O'Keefe looks to be their biggest threat."
Britain's Got Talent 2013 airs at 7PM tomorrow night on ITV.
