Laurel and Hardy were a British-American comedy team during the early Classical Hollywood era of American cinema, consisting of Englishman Stan Laurel (1890–1965) and American Oliver Hardy (1892–1957). Starting their career as a duo in the silent film era, they later successfully transitioned to "talkies". From the late 1920s to the mid-1950s, they were internationally famous for their slapstick comedy, with Laurel playing the clumsy, childlike friend to Hardy's pompous bully. Their signature theme song, known as "The Cuckoo Song", "Ku-Ku", or "The Dance of the Cuckoos" was heard over their films' opening credits, and became as emblematic of them as their bowler hats.

A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
