Shave and a Haircut

Rare card · No. 52221

"Shave and a Haircut" and the associated response "two bits" is a seven-note musical call-and-response couplet, riff, or fanfare popularly used at the end of a musical performance, usually for comedic effect. It is used melodically (both in a minor or major key) or rhythmically, for example as a door knocker. "Two bits" is a term in the United States and Canada for 25 cents, equivalent to a U.S. quarter. "Four bits" and "six bits" are also occasionally used, for example in the cheer "Two bits, four bits, six bits, a dollar." In the UK, it was often said as "five bob" (slang for five shillings), although words are now rarely used to accompany the rhythm or the tune.
