Smoking

• Jon: You know, you shouldn't smoke.
• Sam: Right.
• Jon: It will turn your lungs black.
• Sam: What color are my lungs now?
• Jon: I... errr... Well, I don't know.
• Sam: I'll tell you what color healthy lungs are: they're also black. You know why? Because there's no fucking light inside our fucking bodies, therefore everything inside is black!
