"I Started a Joke" is a song by the Bee Gees from their 1968 album Idea, which was released as a single in December of that year. It was not released as a single in the United Kingdom, where buyers who could not afford the album had to content themselves with a Polydor version by Heath Hampstead. This is the last Bee Gees single to feature Vince Melouney's guitar work, as he left the band in early December after this song was released as a single.
