Liar, liar, got your pants on fire 
I know you want it, you know you want it too 
Hey diddle diddle, when the cat wants to fiddle 
The kitten's gotta give him the moon 
And they say "you gotta look before you leap" 
And "we're gonna judge you by the friends you keep" 
But you're looking nasty and I'm in too deep 
You'll be real happy to be losing sleep 
Chorus: 
When your walls come down, when your walls come down 
When your walls come down, you get so crazy when there's no one around 
You got your script from a Cosmo guide, "15 Ways to Find a Lover" 
Don't you make me chase you, cause the author lied 
You'll get your answers, babe, under the covers 
You say "I wanna wait until I'm really sure" 
And "I want a love to last forever more" 
And "I've got my pride, I've got my dignity" 
Well you'll swallow everything when you're with me 
chorus 
When your walls come down, when your walls come down 
When your walls come down, ah, you're so 
(Come here baby and - auw...) 
And they say "you gotta look before you leap" 
And "we're gonna judge you by the friends you keep" 
Listen, you're looking nasty and I'm in too deep 
You'll be real happy to be losing sleep 
chorus repeats out
