<P> The tune has been used innumerable times as a coda or ending in musical pieces . It is strongly associated with the stringed instruments of bluegrass music, particularly the 5 - string banjo . Earl Scruggs often ended a song with this phrase or a variation of it . On the television show The Beverly Hillbillies, musical cues signifying the coming of a commercial break (cues which were in bluegrass style) frequently ended with "Shave and a Haircut". It is the most popular bluegrass run, after the G run . </P> <P> "Shave and a Haircut" was used in many early cartoons, particularly Looney Tunes cartoons, played on things varying from car horns to window shutters banging in the wind . It was also used as an ending to many cartoon shows, just after the credits . Decades later, the couplet became a plot device used by the chief antagonist Judge Doom in the film Who Framed Roger Rabbit, the idea being that Toons cannot resist finishing with the "two bits" when they hear the opening rhythm . </P> <P> The phrase has been incorporated into countless recordings and performances . Notable examples include: </P> <Ul> <Li>' That's a Lot of Bunk', a 1920s novelty song by Billy Jones and Ernest Hare, known as "The Happiness Boys," uses the riff at the end of the song . </Li> <Li> R&B singer and bandleader Dave Bartholomew used the phrase on two of his recordings: "Country Boy" (1950) at the very end, and the original version of "My Ding - A-Ling" (1952) as a figure introducing each verse . </Li> <Li> Les Paul and Mary Ford's Capitol recording of "Magic Melody" concluded with the phrase minus the last two notes ("two bits"). Responding to complaints from disc jockeys, Capitol in 1955 released "Magic Melody Part 2"--consisting solely of the missing notes--on a 45, said to be the shortest tune on record . </Li> <Li> P.D.Q. Bach ends his "Blaues Gras" ("bluegrass") aria with "Shave and a Haircut", sung in Denglisch (mangled German and English): "Rasieren und Haarschneiden, zwei bitte" ("Shave and haircut, two please", ungrammatical in either language). "Zwei bitte" is a Denglisch pun, sounding like "two bits" to a speaker of both languages . The melody is also used in The Short - Tempered Clavier . </Li> <Li> The song "Gee, Officer Krupke" from Leonard Bernstein's musical West Side Story ends with the tune . </Li> <Li> The opening theme to the TV series The Tonight Show Starring Johnny Carson ends with the tune . </Li> <Li> The original version of "Love and Marriage" by Frank Sinatra (recorded for Capitol Records in 1955) ends with the tune . </Li> <Li> "Everything About You", by Ugly Kid Joe (recorded for Mercury Records in 1992), ends with the tune . </Li> </Ul>
