There's a passage in Patrick Süskind's book Die Geschichte von Herrn Sommer where the fictional author, remembering his childhood, tells the story of a fatal piano lesson with Fräulein Funkel. He is playing a duet with her, and keeps playing an F natural instead of an F# at a particular point. She gets angry at him and hits the note several times, saying "That is an F#". Then she has to sneeze. She wipes the snot from her nose with her finger and hits the note several more times. She thus deposits a large booger on the F# key. When they repeat the passage, the boy cannot bring himself to touch the disgusting mess on the key, and therefore in desperation once more plays an F natural. Fräulein Funkel goes into a tantrum of rage and throws him out.
Very funny! But when readying the story I thought the punchline would be that the teacher would sneeze during the recital when he plays F natural so nobody hears the mistake.
