"I'm a Cuckoo" is the second single from Scottish indie pop band Belle & Sebastian's sixth studio album, Dear Catastrophe Waitress (2003).

B-side "Stop, Look and Listen" merges into "Passion Fruit" at the end of a song—an instrumental piece which was performed live prior to its release.

Reviewing the remix, PopMatters said, "the Avalanches’ remake draws out a more organic side with casual wind instruments and warm percussion.

The samples of hustling, bustling chit-chat strike a note of extroverted gregariousness that shy, retiring types like Belle and Sebastian sometimes need someone else to bring out of 'em.

"[3] The video for "I'm a Cuckoo" features Scottish Olympic 100m gold medallist Allan Wells as a running coach and lead singer, Stuart Murdoch, as an aspiring runner.
