Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791) was a prolific and influential composer of the Classical era. He composed over 600 works, many acknowledged as pinnacles of symphonic, concertante, chamber, operatic, and choral music.

When Lois considers looking for work in "Peter Problems", Peter decides that it may give him time to expand his record collection. In an ensuing cutaway, he considers purchasing albums by Mozart, Johann Sebastian Bach and Claude Debussy.
