Takes One To Know One

Katy Perry

What are you lookin´ at?
(Yeah)

I saw this coming 
From a mile away
I saw a crack 
In the egg
A little rip 
In the page

I found 
Your necklace 
On the floor
Underneath the bed
Where you said
I was the only one

You thought i´d cry
(You-thought-i´d-cry)
You thought i´d lay 
Down and die
You thought 
There´s no 
Hetting over you
(Ha-ha)

And all this time
(All-this-time)
You´ve been having 
Your fun
I´ve been having 
Some fun too

Cause´ it 
Takes one to know one
Congrats 
You´ve met your match
You think I´d lie here 
Heartbroken
But the knife 
Is in your back
(In-your-back)

You left your suit 
You left your tie
And looked me in the eye
And swore that it 
Was business baby
(Yeah right)

And when you left 
I got a call
That started it all
And now 
It´s not your business 
Ba-by

You thought i´d cry
(You-thought-i´d-cry)
You thought i´d lay 
Down and die
You thought 
There´s no 
Getting over you
(Ha-ha)

But all this time
(All-this-time)
You´ve been having 
Your fun
I´ve been having 
Some fun too

Cause´ it 
Takes one to know one
Congrats 
You´ve met your match
You think i´d lie here 
Heartbroken
(I´d-lie-here)
But the knife 
Is in your back
(In-your-back)

You´re such a wreck
The cutest accident
Makes so much sense
You´ll come 
Back to me 
Oh
(Ahhhh)

And i´ll let you

Hey
Huh 
You´re back

Cause´ it takes one 
To know one
Congrats 
You´ve met your match
You think 
I´d lie here 
Heartbroken
(I´d-lie-here)
But the knife 
Is in you´re back
(In-your-back)

Cause´ it 
Takes one to know one
(Hi, nice to meet you)
Congrats 
You´ve met your match
You think 
I´d lie here 
Heartbroken
(I´ll-lie-here)
But the knife 
Is in your back
(In-your-back)
