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)
