- Keller, Exterminator: All the bugs in your bathroom are dead
- Capt. Barney Miller: Thank you Mr Keller
- Keller, Exterminator: Don't mention it, they were dead already
- Capt. Barney Miller: How about the bugs in my squad room ?
- Keller, Exterminator: Oh, I got to remove some of the molding over there and in a couple of hours there will nothing that can move
- Capt. Barney Miller: I hope you're referring to the insects
- Keller, Exterminator: What do you think, I spray people ? I'm a professional
- Capt. Barney Miller: A small attempt at humor
- Keller, Exterminator: You know, I got the power of life and death over these creatures. They live in fear of me alone, I'm their God, their master
- Det. Stan 'Wojo' Wojciehowicz: There's another one
- Keller, Exterminator: I'll be right there
