I can see us parked in front of my old house
First time that we kissed almost knocked me out
'Cause it stole all the breath straight from my lungs
And it hit me like a sucker punch

Never left your side, never left this town
Everybody said you'd never settle down
But you gave me a ring, said I was the one
And it hit me like a sucker punch

Thought we were the champions
Thought we were the type
To never throw the towel in, never lose a fight
Didn't hear the train 'til it hit me from behind
Feeling like a fool now
'Cause it caught me by surprise
When you laid it on me all at once
It hit me like a sucker punch

Yeah, you always said she was just a friend
Funny over time how the truth can bend
Yeah, you swore up and down, only happened once
And it hit me like a sucker punch

Thought we were the champions
Thought we were the type
To never throw the towel in, never lose a fight
Didn't hear the train 'til it hit me from behind
Feeling like a fool now
'Cause it caught me by surprise
When you laid it on me all at once
It hit me like a sucker punch

Guess I always thought you would change your mind
Got a little drunk, looked you up tonight
Saw you married that girl
Got a boy coming in six months
And it hit me like a sucker punch

Thought we were the champions
Thought we were the type
To never throw the towel in, never lose a fight
Didn't hear the train 'til it hit me from behind
Feeling like a fool now
'Cause it caught me by surprise
When you laid it on me all at once
It hit me like a sucker punch
