I'm the one who knocks

Jesse
Do you want to build a meth lab?
Come on let's go and cook
I never see you anymore
Come out the door
Let's make our product by the book!
We'll make lots of money
Just you and me
We'll stack the cash up high!
Do you want to build a meth lab?
A rolling Rv meth lab

Jesse: Go away, Mr. White

Walter: Just one try
Do you want to build a meth lab?
Or dodge some of Gus' calls?
I think some cook time is overdue
I've started talking to the money in the walls
(Look there, Holly!)
It gets a little lonely
In this empty lab
Just watching that fly whiz by
(Buzz buzz buzz buzz buzz buzz buzz buzz)

Jesse, please
I know you're in there
Badger's asking where you've been
This can't all be for nothing
And I'm trying to
Make things right with you
Just let me in
We built this empire together
And it's all we have
What do you want to do?
Do you want to build a meth lab? (cough)
