King Arthur: Merlin has demonstrated his power. Now you must offer proof of yours, or for having falsely claimed the gift, forfeit your life.
MacGyver: You guys don't mess around, do you?
King Arthur: Show us some good magic, Stranger. Some magic of creation. Or by this court you must die.
MacGyver: You guys are so strict.
MacGyver: I don't suppose anyone has a pestle?
Merlin: I am an alchemist. My cloak is my laboratory.
Merlin: Unhand me, I say, traitorous toadstools! Unhand me this instance or I'll turn you into dragon drunge!
Merlin: Dragon drunge.
MacGyver: You're going to have to tell me what that means some day.
MacGyver: So I'm making an electrophoresis.
Merlin: Is that Greek?
MacGyver: No, it's a machine.
Merlin: What's a machine?
MacGyver: I knew you were going to ask that.
MacGyver: All right, here goes nothing. Keep your fingers crossed.
Merlin: "Here goes nothing." "Keep your finger crossed." My life is in the balance and you talk riddles?
MacGyver: Cliches, actually.
Merlin: What kind of a fool do you take me for?
MacGyver: An innocent fool, Merlin.
