Tuco Salamanca : [about Walter and Jesse's latest batch of meth] What is this? It's blue.
Walter White : We used a different chemical process, but it is every bit as pure.
Jesse Pinkman : It may be blue, but it's the bomb.
Tuco Salamanca : [sniffs a sample and gasps] Tight, tight, tight! Oh... blue, yellow, pink! Whatever, man, just keep bringing me that!
Tuco Salamanca : You're doing business like a couple little bitches.
Walter White : I want all of it. 70 grand.
Tuco Salamanca : What did you say?
Walter White : You like this product. And you want more. Consider it a capital investment.
Tuco Salamanca : [getting in his face] Look, old, bald motherfucker. Fifty-two and a half, 25 points vig.
Walter White : Vig?
Jesse Pinkman : Interest, weekly.
Walter White : Okay. That's $65,625 with interest. 1.875 pounds.
Tuco Salamanca : No, two pounds. Next Friday, and no production problems.
Walter White : Can you handle four pounds?
Tuco Salamanca : Listen, old man. Talk is talk. But owing me money, that's bad.
[he hurls a wad of bills at Walt, then dumps the rest on the ground]
Jesse Pinkman : [watching Tuco and his thugs leave] What did you just do?
