Baba: (on MacGyver) It is written, another stranger will follow the first. A resourceful man. He is drawn to this abomination and to our destiny. He will come from the sky, out of the West.
MacGyver: You're okay!
Jack: You came for me.
MacGyver: Thank God you're all right.
Jack: Yeah, yeah.
MacGyver: Nothing's broken.
Jack: No. I'm fine.
MacGyver: Oh great. Now I can break your neck!
MacGyver: What I can't figure is how you conned Pete and the entire Phoenix board into underwriting this scheme of yours.
Jack: "Scheme?" Who said it was a scheme?
MacGyver: I did. Just now. Didn't you hear me?
Jack: This is a mystical place. You got to go with the flow.
MacGyver: Well for me, the flow is that way.
Mukti: Something wrong, MacGyver?
MacGyver: Oh, not yet. But I can feel it coming.
Jack: You're getting us involved in trouble, Mac.
MacGyver: Well, that's kind of a switch, isn't it?
Mukti: What do these H-bombs do?
Jack: Kill people. Just one will wipe out a city the size of New York.
Mukti: Why would the Kabustanis want such a fearsome device?
Jack: Power. Greed.
MacGyver: Insanity. Welcome to our world.
MacGyver: I'll be right back.
Jack: I hate it when he says that. I hate it!
MacGyver: You lied to me, Jack.
Jack: Never. About what?
MacGyver: If I don't make it back, that tape has got to make it to the U.N.
Jack: And you trust me? What a switch!
