Hardy is fond of wordplay, and a key element in this song is a clever twist on a classic nursery rhyme. In the schoolyard chant "K-I-S-S-I-N-G," kids like to embarrass potential couples with the taunt:[Name] and [Name]
sitting in a tree,
First comes love,
then comes marriage,
then comes the baby
in a baby carriage!
Hardy rewrites the rhyme to reflect how fast the teen couple's lives change when they're faced with the grown-up responsibilities of raising a child. He sings:A boy and a girl and a three on the tree
First comes lust, then the shotgun marriage
Six months later come a baby in a carriage
In a 2020 Songfacts interview
, Hardy recalled when the nursery rhyme idea sprang up in the writers' room: "I don't know who brought that up first, but I love doing weird stuff like that - that's my jam. So, as soon as somebody was like, 'K-I-S-S-I-N-G,' I remembered, 'Yeah, then there's more after that - there's like first comes love, then comes marriage, then comes baby in a baby carriage,' so we looked it up to make sure I was right and we just ran with it."
