John Lennon got the title of the song, “Happiness is a Warm Gun,” from an NRA advertisement he saw in a magazine. The full quote “Happiness is a warm gun in your hand” was the working title of the song. The idea of a warm gun (meaning that it was just fired) being the object of happiness was a little shocking to Lennon. He thought a love song for one’s gun would be a great exercise in irony. This is ironic in a lot of ways, not only because of Lennon’s death by gun violence, but the fact that he may not have known that the advertisement itself was a parody of a Charles Schultz Peanuts books,Happiness is a Warm Puppy. This Beatles’ song is a parody of a parody.
