Music by Carter Burwell. This is the celebrated Diaper Robbery sequence from “Raising Arizona,” a Coen Brothers film.
Nicholas Cage plays an ex-con who has vowed to his wife, Holly Hunter, not to stick up stores ever again (though they have kidnapped the baby, to raise as their own). At any rate, she gets mad at him when he sticks up a Quickie Mart.
Notice a nice postmodern touch: the “Raising Arizona” music is playing in both stores that Cage goes into, in muzak versions.
Remember: It ain’t armed robbery if the gun ain’t loaded.
