Murdoc: Of all my past adversaries, MacGyver, you've always been the most creative.
MacGyver: (trying to open a door) The lock only opens with Nicholas' thumb print.
Murdoc: Oh, yeah. Maybe this will open it. (pulls out a grenade)
MacGyver: Murdoc, we had a deal.
Murdoc: But, you, you said no guns.
MacGyver: Don't split hairs with me.
Murdoc: Oh, God, no. Snakes. Oh, snakes. I hate snakes, MacGyver.
MacGyver: Well, I'm not too crazy about them myself.
MacGyver: You know, I'm not real big on doing favors for professional killers.
Murdoc: They've kidnapped someone very close to me, MacGyver.
MacGyver: Someone is close to you?
Murdoc: You know, MacGyver, that's why you're so hard to beat. Nobody knows what you're going to do next—including you.
