"Why Don't You Get a Job?" is a song by American rock band the Offspring.
The song is the 11th track on the Offspring's fifth studio album, Americana (1998), and was released as its second single on March 15, 1999. The song also appears as the eighth track on the band's Greatest Hits album (2005). The single peaked within the top 10 of the charts in several countries, including reaching number two in the United Kingdom, Australia, Iceland, and Sweden.
The song drew attention for its close similarity to the song "Ob-La-Di, Ob-La-Da", as multiple music writers pointed out that the melody and rhythm sounded much like the Beatles' 1968 release from their self-titled double album (also known as the "White Album").
