The interesting thing (for me) about that quote is the melody is picked up by the Music Man's love interest but she uses different words. I'm not sure if either is aware of the other's involvement.Spike in OMWF: 'The day you suss out what you do want, there'll probably be a parade. Seventy-six bloody trombones.'
