Krysztof Werkowicz is a tuba player and variety act who auditioned for Series 14 of Britain's Got Talent.
In his audition, Werkowicz began by playing the Tuba to a classical piece, however he then began to play to 'Fireball' by Pitbull, with balls of fire appearing from the end of his tuba. His performance was buzzed off just as it reached its finale, which involved a continuous stream of fire exiting the tuba. He was sent home during the audition stage of the competition.
His audition was shown as part of a montage of 'Bad Acts' alongside Emmanuel Vass, Dawn Xiana Moon, Patch, and Jack Beavis, before the successful audition of Håkan Berg.
