I like livin' in the land of free
And I like how it feels when you lean on me
Ever since you wandered into my back yard
I dropped my resistance, lowered my guard
You got the pieces of my heart all in a row
Knock one down and the whole thing goes

It's the domino theory of love
It only takes a shove
I fall, you fall
We gotta keep our defenses up
That's the domino theory of love

The game of romance is a balancing act
It's two steps forward and one step back
Take a little liberty, give a little ground
Next thing you know we'll be sliding on down
When it comes to sortin' out our hearts and our minds
We're just a couple of pushovers standing in line

It's the domino theory of love
It only takes a shove
I fall, you fall
We gotta keep our defenses up
That's the domino theory of love

When it comes to sortin' out our hearts and our minds
We're all a bunch of pushovers standing in line

It's the domino theory of love
It only takes a shove
I fall, you fall
We gotta keep our defenses up
Or we'll all go down together
It only takes a shove
I fall, you fall
We gotta keep our defenses up
