"Less Than Zero" is the eighth track on Elvis Costello's debut album My Aim Is True, and the first Costello single that Stiff Records released.
In the liner notes to the Rhino edition of the album, Costello writes: The song therefore fits in with a number of anti-fascist protest songs on early Costello albums, which also include "Night Rally" from This Year's Model and "Goon Squad" from Armed Forces. In this case, a racist and totalitarian movement is seen in terms of sub rosa teenage sex: "Turn up the TV... Even your mother won't suspect it/ No your father won't know."
On his first visit to the United States, Costello substantially rewrote the lyrics to refer to Lee Harvey Oswald. This was a reference to the common misconception among American fans that this was the "Mr Oswald" referred to in the original lyrics. This version is usually referred to as the "Dallas version" and is available as a bonus track on the My Aim is True reissue.
The song later provided US author Bret Easton Ellis with the title of his debut novel.
