Jack: Have you ever had a blood transfusion?

Sawyer: What? No.

Jack: Taken pills for malaria?

Sawyer: Nope.

Jack: Have you ever had sex with a prostitute?

Sawyer: What the hell has that got to do with anything?

Jack: Is that a yes?

Sawyer: [sighs] Yes.

Jack: Have you ever contracted a sexually transmitted disease? [Sawyer doesn't respond.] I'm going to take that as another yes. When was the last outbreak?

Sawyer: Go to hell, Doc. [Sawyer exits.]

Kate: I know he deserved it, but...

Jack (grinning): He needs glasses.
