Angus MacGyver: Can you get that?
Jack Dalton: I can, but I won't.
Angus MacGyver: Are you serious? Why not?
Jack Dalton: House rules.
Angus MacGyver: House rules—what does that even mean?
Jack Dalton: It means it's your house. You got to answer the door. What's the matter with you? That's proper etiquette.
Sarah Adler: (to Jack) I'm just gonna stop you right here before you say something we both regret, because you'll be sterile and I'll be in jail.
