- Professor Anthony: I trust there hasn't been an accident?
- Trooper Ross Martin: Not an accident, Sir. A murder.
- Nan: A murder! Not near here?
- Trooper Ross Martin: Right up the road, Miss Anthony. Just a couple of gangsters. They turned on a smokescreen and got away.
- Nan: Smokescreen? What's that? Oh, I'm petrified.
- Professor Anthony: The modern criminal has become a versatile fellow, hasn't he, Martin?
- Trooper Ross Martin: He certainly has, Sir. Uses flop-over licence plates and..
- Nan: Flop-over what?
- Trooper Ross Martin: Car licence plates. If we're hunting a Michigan car, they sometimes flopover to Indiana plates after the first half mile and sail right past.
- Professor Anthony: Gangsters! Up Here! Smokescreen. Smokescreen? Yes. Who would believe that this was anno domini 1935?
- Trooper Ross Martin: Well, I'm sorry to go Sir but I have to shakedown all the garages and barns round here looking for that car.
- Nan: Shakedown? Oh, that would be thrilling. Think of going back to Boston and telling our friends that we'd been shaken down!
- Nan: Oh, my dear Nan do be serious and remember that this is a ghastly business.
- Nan: Oh, Daddy, please let him shake us down! Just this once.
- Professor Anthony: You see, Martin. My daughter enjoys a thrill. It's probably due to the sheltered life she's led.
- Nan: [to Martin] Come on, I'll show you our garage. I can just see the headlines: "Police search Professor's garage." What colour car was it?
- Trooper Ross Martin: Light grey. Well goodbye, Professor. And thanks for the use of the phone.
- Sgt. Barrel: [Training new police recruits] Now that finishes the studying of handcuffs. And, by the way, speaking of handcuffs, are any of you fellas thinkin' of gettin' married? Well, stop thinkin'. You can't do it in this outfit. Not for a year anyhow. And never, if I have my way. And that's a mighty good regulation too. Keep away from women.
