The pink panther in 'pink at first sight' (1981)

It is Valentine's Day and the hip feline has no love and no money except for seven cents. He goes to a messenger service for a job but messes his rehearsal up. He then buys a cassette player and pre-recorded cassettes with the seven cents he had left and goes back to the messenger service miming to "Vesti la giubba", an aria from Ruggero Leoncavallo's opera Pagliacci, and gets hired as a messenger on Valentine's Day
