Tandem bicycles are sometimes called "Daisy Bells". This is in reference to "Daisy Bell (Bicycle Built for Two)" which is a popular song, written in 1892 by British songwriter Harry Dacre, with the well-known chorus, "Daisy, Daisy / Give me your answer, do. / I'm half crazy / all for the love of you", ending with the words, "a bicycle built for two".
