Piganini is a pig violinist who appears in The Ghost of Faffner Hall episode "Music Is More Than Technique".

Locked away in a closet, a janitor (played by Ry Cooder) happens upon Piganini, who has stage fright before his performance. He's perfectly content to play his scales, but feels pressure that the audience wants him to play a musical composition. The janitor teaches him how to put the notes from his scales into a melody, and plays "Pig Foot Shuffle" on his guitar.
