Nobody knows that I am a secret spy 
I follow you home, careful to walk behind you 
I climb up your tree and hide in the leaves 
To keep you from seeing who I am 

Call me obsessed, but I need to know your name 
Your age, your address and where in the world you came from 
It's silly to think that I'm on the brink 
Of falling right off my rocker 

Oh, I want to know 
All about your mom and your favorite song 
And why you hypnotize me 
Well, I tell you what 
I'm the definition of obsessive-compulsive, crazy love 

Late after dark, your light is on upstairs 
And I watch you dance as if you were Fred Astaire 
A little finesse, a sparkly dress 
And I could be Ginger Rogers 

Oh, I want to know 
All the books you read and your favorite sweets 
And why you hypnotize me 
Well, I tell you what 
I'm the definition of obsessive-compulsive, crazy 

La, la, la I'm like a firefly 
La, la, la in the evening sky 
I'm all aglow whenever I see you walking by 

Oh, I want to know 
If you ever plan to hold my hand 
And why you hypnotize me 
Well, I tell you what 
I'm the definition of 
Obsessive-compulsive crazy love
