Jack Dalton: Hold it, Mac.
[Jack pours out the water from the Fountain of Youth]
MacGyver: What are you doing?
Jack Dalton: I can't promote a bottling plant here. It'd create a media circus. Con men and two-bit developers would converge like buzzards on a fresh road kill. You dont mess with perfection, Mac. Bad karma.
Jack Dalton: Mac!
MacGyver: Jack! You're okay!
Jack Dalton: You came for me!
MacGyver: Thank God. You're all right.
[after seeing the crash site of Jack's plane]
Jack Dalton: Yeah, yeah.
MacGyver: Nothing's broken?
Jack Dalton: No, I'm fine.
MacGyver: Oh, Great. Now I can break your neck!
