"Everybody Works but Father" is a popular song published in 1905, with words and music by Jean Havez.
The song was introduced and recorded by blackface performer Lew Dockstader.
[1] The song was sufficiently popular that it inspired a "sequel" titled "Uncle Quit Work Too", about a mooching relative who "sits around the house with about a half a souse and he never does a doggone thing."
It was in the repertoire of Groucho Marx, who would include the song with a segment he performed about fathers.
In The Worst Journey in the World, Apsley Cherry-Garrard remembers that some of the men on the Terra Nova expedition would sing it as a joke about Victor L. A. Campbell, the only father aboard and one who was generally found hard at work.
