Angus MacGyver: We're safe.
Jack Dalton: Safe? What is safe about giving a knife to a monkey? Do you have any idea what that could do?
Angus MacGyver: I don't know, Jack.
Jack Dalton: What? You probably just started Planet of the Apes, man.

Jack Dalton: Senior year, when he beat me out for homecoming king I was never the same after that.
Angus MacGyver: Well, you do know that homecoming Kings - hold no real power, right?
Jack Dalton: Just sayin', this punk really shook my confidence.
Riley Davis: Well, he may have, Jack, - but this was years ago.
Wilt Bozer: Decades.
Angus MacGyver: Centuries, even.
Jack Dalton: Yeah Oh, very funny.

Matilda Webber: But one aspect of the competition has always remained the same. Our team has never won. But this is our year.
Wilt Bozer: Yeah.
Matilda Webber: The year that the Phoenix takes home the blue ribbon, and all the black budget funding that comes along with it.

(re: Allie Winthrop)
Wilt Bozer: So, when did you two hook up?
Angus MacGyver: What?!…Yeah, fine.

Matilda Webber: All set?
Angus MacGyver: All set.
Matilda Webber: If your robot doesn't win, you're all fired. Best of luck.

Angus MacGyver: But in order for this to work, we got to be within 160 feet. So you know what to do, Boze.
Wilt Bozer: Absolutely not.

Allie Winthrop: Hey, you okay? You jumped out of a stolen vehicle onto a killer robot, and stared down an F-22 with orders to fire.
Angus MacGyver: Yeah, I also smashed my phone.

Wilt Bozer: Nothing crazy about wanting the world to be a more peaceful place.
Jack Dalton: You mean except for the part where he hijacked a military drone and tried to attack the Pentagon with it to make his point?
Angus MacGyver: Yeah, except for that part. Shut up.
Jack Dalton: You shut up.

Wilt Bozer: Is it weird that I'm kind of offended that he didn't hack our drone?
Angus MacGyver: Super weird.

Jack Dalton: I know I'm not your grandpa or anything, but
Angus MacGyver: But you're almost old enough to be?
Jack Dalton: You looking to get popped in the mouth?
Angus MacGyver: Saw an opening.

Jack Dalton: But losing gave me the sense that I have something to prove, you know? It kind of fueled the rest of my life. It's probably why I joined the Army, became a Delta, applied for the CIA.
