We hear the classic 1950s song: "Put Your Head on My Shoulder" by Paul Anka, as we see a romantic scene play out where someone puts their head on their significant other's shoulder, but that significant other is wearing a navy blue or black shirt, blazer or cashmere sweater, and the person who put their head upon said shoulder lifts their head up off the other person's shoulder, leaving behind proof of their having put their head there in the form of copious quantities of dandruff flakes.
This is Paul Anka performing: "Put Your Head on My Shoulder" in 1959:
