Black Joke

The Black Joke, sometimes spelled Black Joak, was a bawdy song heard in London around 1730. William Hogarth referenced the song in the Tavern Scene of A Rake's Progress. Grose's dictionary of the vulgar tongue notes that the refrain of the song was "Her black joke and belly so white", with black joke referring to female genitalia. Historical fiction writer Patrick O'Brian, in "Master and Commander ("the first of his 21-novel Napoleonic War series, originally published in 1969) referenced the ditty being sung aboard a sloop, the Sophie, that—in this fictional account—was in the service of the Royal Navy in 1800. The lyrics and tune apparently gave rise to variations from 1730 onwards, such as the "White Joak" and so forth. The tune was later known as "The Sprig of Shillelagh". Thomas Moore (1779–1852) wrote the song "Sublime was the warning which Liberty spoke" to the tune.
