When MacGyver and Bill are driving the truck to the abandoned strip mine to look for dynamite, Mac is wearing sunglasses. Then suddenly, in close-up shots, the sunglasses are gone. As the truck arrives at the mine and Mac gets out, he suddenly has the sunglasses back on again.
In the scene where MacGyver and Bill are entering the shack to get the dynamite boxes, right after Bill steps off the board onto the shack's floor, there's a shot of him walking towards the dynamite boxes. The gloved hand of one of the production crew clearly comes into the right side of the shot to steady a dynamite box.
MacGyver's hands are shown to be dirty in long shots, but clean in close-ups, when he works on the truck engine.
The bit where MacGyver fixes the fuse box by wrapping the burnt-out fuse with a chewing gum wrapper does actually work as confirmed by Mythbusters.
MacGyver: (needing to straight Torgut's broken leg) Of course, you know we're going to have to give it a pretty good yank to straighten it, get a splint on it.
Torgut: Well, what are you waiting, Doc? Let's do it!
MacGyver: Oh, I was just wondering...
Torgut: Do you have any doubts you can do it?
MacGyver: Oh, no, that's no problem. It has to do with Curie's Law.
Torgut: Curie's what? Curie's Law?
MacGyver: Yeah. You know, the one that say the magnetic susceptibility of a paramagnetic substance is inversely proportional to the absolute temperature. You know.
Torgut: The magnetic susceptibility of the...
(MacGyver abruptly straightens his broken leg)
MacGyver: On the other hand... don't think about it.
Torgut: Oh... whew. You're real slick, MacGyver.
MacGyver: Well, naked dancing girls might have been a little better, but... you know.
Bill: (carrying unstable dynamite) You ever drop one of these?
MacGyver: Not recently. You?
Bill: Well, in Tulsa, Oklahoma, a guy once bet me that I couldn't balance a stick of burning dynamite on my forehead.
MacGyver: Yeah, what happened?
Bill: Blew my head off.
MacGyver: Uh, wait a minute, here.
Bill: He's thinking. I can hear the gears grinding away.
MacGyver: Well, I guess I'm going to have to entertain a couple of theories a few of my buddies came up with a while ago. Archimedes and Euclid, you may have heard of them.
MacGyver: I've been wanting to take a nice long vacation, a little rest and relaxation. Spend some time with friends, party down.
Bill: You've always got an answer.
MacGyver: It doesn't always work.
Bill: You are crazy! I mean, certifiable!
MacGyver: Yeah? What does that make you?
Bill: You know, back in the 1920s, they used to truck nitro out to the fields.
MacGyver: They used to call that the suicide run, didn't they?
Bill: You scared?
MacGyver: You bet.
Bill: Me, too. Ain't it great?
Bill: Pure nitro—that stuff'll go off if you sneeze.
MacGyver: Let's try not to sneeze.
MacGyver: You know this building is coming down with the first strong wind?
Bill: Hey, you want to live forever?
MacGyver: Thinking about it.
MacGyver: Maybe we oughta consider puttin' it out ourselves.
Bill: With what?
MacGyver: Know-how. Ingenuity… Dynamite wouldn't hurt.
Laura: I asked him to make a choice: hellfighting . . . or us.
MacGyver: He chose right.
MacGyver: [I am] a man of many, many, many, many, many, many talents.
MacGyver: Some people say that there are no more frontiers left for us to conquer. But then again, some people still go out into the wilderness in search of their dream.
MacGyver: You got a spare fuse?
Laura: You're holding it.
Bill: You can forget about the new truck. I'll take a dozen of those ballpoint pens.
MacGyver: This road would definitely be an E ride at Disneyland.
