Riggs : (Riggs and Murtaugh are sitting in the Captain's office, Riggs is smoking. They both are told that their next assignment will be babysitting a witness) What are we supposed to do with this guy?
Captain Murphy: How the hell should I know? Take him to Disneyland.
Riggs: Oh, this stinks. This stinks.
Captain Murphy: I don't give a f***, Riggs. That's why I don't have an ulcer, because I know when to say I don't give a f***. Here's where he's staying. It's a nice hotel. All the expenses are being picked up by the justice department, so just enjoy yourself. And Riggs, one more thing.
Captain Murphy: (the captain throws a no smoking sign at Riggs) You know what that says?
Riggs: Yeah, yeah, same thing as that. (points to another no smoking sign on the door) But I don't give a f***.
