Lawrence "Loz" Nannigans, a member of the comedy/music group Shonky Brothers, said in a Reddit post he was recording farts to send to his brother when he noticed the "major seventh arpeggio in the key of b flat, with a trill at the end" emerge from his backside.

This would have been in the first dozen or so, but the second it came out I knew it was special," he wrote. Nannigans, who posted the slowed-down version of his fart to YouTube with a flute version of the same music for comparison, dubbed the recording "my Magnum Anus" and "rectum opus." "I fear my best work is now behind me," he wrote in the video's text.
