Breaking Bad, Season 5

[Walter, Jesse, and Mike drive away from the APD outpost after using an industrial magnet to wreck an evidence room.]

Jesse:
Yeah! Bitch!

Mike:
Shut up!

Jesse:
Oh! Yeah!

Mike:
What exactly are you celebrating? You left the truck behind!

Walter:
So what?

Mike:
"So what?" So what if they find prints? What if they trace it back to the wrecking yard?

Walter:
They won't. There's no prints. I made sure of that. There's no paperwork on the truck, the magnet, or the batteries. Untraceable salvage, all of it. I made sure of that, too.

Mike:
Well, you got all the answers. So you tell me, answer man: did all that even work just now?

Walter:
Yes. It worked.

Mike:
I'm supposed to take that on faith, yeah? Why? How do we know?

Walter:
Because I say so.
