In the opening war game sequence, MacGyver dodges an authentic explosion from incoming artillery, which is something no one would ever use in a friendly wargame as presented here.
Although the egg in the radiator trick theoretically could temporarily seal minor radiator leaks (but not bullet holes), the seal would soon break.
Kelly: My mom died right after I was born.
MacGyver: Any brothers or sisters?
Kelly: No. I guess I'm his daughter and his son.
MacGyver: Which one of you is here to rescue him?
MacGyver: Egg whites are good for a lot of things. Lemon meringue pie, angel food cake, and... plugging up radiators.
MacGyver: I hope you didn't take what happened back at the road block personally.
(An officer hits him in the stomach.)
MacGyver: (in pain) Guess you did!
Pete: Diversion worked? We're home free.
MacGyver: No, timer worked. We're not done yet.
(After Pete hands him a gun)
MacGyver: You know how I feel about those things.
Pete: But you're defenseless out here.
MacGyver: No, just weaponless.
MacGyver: There are times you can't do a job all by yourself. What I needed was a little help from the locals—local chickens, that is.
Raoul: I've been told there's no real proof of his guilt.
Salazar: The problem is being corrected as we speak.
The idea of using an egg to seal a radiator was submitted by a youth as part of the show's policy of accepting fan 'MacGyverisms' and awarding money if used in an episode.
