Danny and Steve in “Unfinished Business”

Danny

[after Steve gets orders from Governor Denning to investigate a case] Is this official business, or is this a favor?

Steve

What difference does it make?

Danny

Well, it makes a very big difference, you see, because official business is, uh, official. A favor is like a quid pro quo kind of deal, right? You solve this murder case for me, and I will give you, uh, oh, five days' paid vacation. Right? Or tickets to Monster Truck Jam, or whatever.

Steve

Monster Truck Jam's not in town.

Danny

Okay, so then it is, indeed, official business.

Steve

Exactly.
