"Shave and a Haircut" and the associated response "two bits" is a simple, 7-note musical couplet popularly used at the end of a musical performance, usually for comic effect. The first known occurrence of the tune is from an 1899 Charles Hale song, "At a Darktown Cakewalk", while it wasn't until a 1939 song (with Milton Berle) "Shave and a Haircut - Shampoo", which used the notes near the end, that the brief tune had lyrics.
