Now we live in the same house As your mother in 1989 I still laugh at the same jokes All the ones that just piss you off the most But in the summertime, baby, we're on fire In the summertime, baby, we're on fire You're the light in the dark, you're on fire Go on and set my world on fire We grew up in the same town You know these roads like the back seat of your car And I still get lost on side streets And we still argue on what you want to eat But in the summertime, baby, we're on fire In the summertime, baby, we're on fire You're the light in the dark, you're on fire Go on and set my world on fire I like to pick you up from work We notice houses we've never seen before I feel empty without you Like half of me don't exist and that's not cool But in the summertime, baby, we're on fire In the summertime, baby, we're on fire You're the light in the dark, you're on fire Go on and set my world on fire You're the light in the dark, you're on fire Go on and set my world on fire
