Natalie: Yeah, look, Mr. Monk, I have to tell you something. I made a decision. If you want to keep following Mrs.
Brody, I suppose that's your right. Although it really isn't. But I can't help you anymore.
Adrian Monk: Why not?
Natalie: I'm just not comfortable. Her husband fired us.
Adrian Monk: It's what they call pro bono.
Natalie: No, pro bono is for lawyers. This is stalking.
Adrian Monk: No, this is comeuppance. Pro bono comeuppance.
Natalie: No, that is just crazy talk.
Adrian Monk: It's not crazy talk.
Natalie: Pro bono comeuppance? It's craziest talk there is. You heard what he said. He wants you to quit.
Adrian Monk: I wanted him to quit! I begged him to quit 40 years ago in stall number three.
