[Marty compliments Nigel on his tee shirt]
Nigel Tufnel: You like this?
Marty DiBergi: It's very nice. It looks like hollow wood.
Nigel Tufnel: This is my exact inner structure, done in a tee shirt. Exactly medically accurate. See?
Marty DiBergi: So in other words if we were to take all your flesh and blood...
Nigel Tufnel: Take them off. This is what you'd see.
Marty DiBergi: It wouldn't be green though.
[Nigel points at Marty]
Nigel Tufnel: It is green. You see how your blood looks blue.
Marty DiBergi: Yeah, well that's just the vein. That's the color of the vein. The blood is actually red.
Nigel Tufnel: Oh then, maybe it's not green. Anyway this is what I sleep in sometimes.
