Happiness Is a Warm Gun is a song by The Beatles featured on the eponymous double-disc album The Beatles also known as The White Album. It is primarily a John Lennon composition, credited to Lennon/McCartney. The original working title of the song was "Happiness Is a Warm Gun in Your Hand," which was inspired by a magazine containing the phrase, which in turn parodied "Happiness Is a Warm Puppy," a Peanuts book written and illustrated by Charles Schulz in 1962.
