- Maxwell Smart: Let's see what Control has given us in their Newlywed kit.
- Maxwell Smart: [opens suitcase and takes out each item one at a time] Throwing knife. Knockout drops. Revolver. And brass knuckels. This must be the Commando kit.
- Maxwell Smart: [opens another suitcase] Ah, this is the Newlywed kit.
- Maxwell Smart: [takes out each item] Toothpaste. Throwing knife. Knockout drops. Revolver. Brass knuckles.
- Dr. Drago: And now Mr. Smart, it is your turn to hear my sonata of death. But before I begin, do you have any last request?
- Maxwell Smart: Do you know any showtunes?
- Professor Sontag: How did this melody go?
- Maxwell Smart: Well, have you ever heard the song 'Heart of my Heart'?
- Professor Sontag: Yes.
- Maxwell Smart: That wasn't it
- Maxwell Smart: But what you didn't know, is that 99 and I were following you to Drago's place in a Control tracking car, did you?
- Professor Sontag: Not until I caught you in my rear-view mirror.
- Maxwell Smart: When was that?
- Professor Sontag: Just after you crashed into the rear end of my car.
- Chief: Now our one clue is the melody you heard just before the murder. Arrick, is the Detect-O-Tune ready?
- Arrick: Yes, Chief.
- Chief: Good.
- Maxwell Smart: How does it work?
- Arrick: Well, the Detect-O-Tune can reconstruct any melody in the same way that a criminal's face can be reconstructed through the descriptions of witnesses. Now, can you remember any of the notes that you heard?
- Chief: Just hum anything you remember, Max.
- Maxwell Smart: Ok, let me see now, Chief.
- [begins humming]
- Maxwell Smart: Daaa, daaa, daaa, daaa, doo, daaa, daaa...
- [Arrick then slowly plays same notes on Detect-O-Tune]
- Maxwell Smart: A little faster than that.
- [Arrick plays notes faster and faster and quickly gets carried away]
- Chief: ARRICK!
- Arrick: Sorry, Chief.
- Chief: Try to get it, Max. This may be vital!
- Maxwell Smart: All right, Chief. Let me see.
- [begins humming]
- Maxwell Smart: Daaa, daaa, daaa, daaa...
- Arrick: [humming along] Bom, bom, bom, bom...
- Maxwell Smart: No, no, no. Daaa, daaa, daaa, da-da-dee, daaa, daaa...
- Chief, Arrick, Maxwell Smart: Daaa, daaa, daaa, dee, daa, dee-dah...
- [All three start singing]
- Chief, Arrick, Maxwell Smart: "Heart of my heart, how I love that melody, love the melody, heart of my heart, brings back a memory!"
- [Max and Arrick realize what they're doing and stop singing, Chief gets carried away and continues singing]
- Chief: "When we were kids on the corner of the street, we were rough and..."
- [Chief stops singing, noticing the others have stopped as well, Max takes out a notebook and starts writing something]
- Chief: What are you doing, Max?
- Maxwell Smart: I'm putting you down for the lead in "The Spy Frolics", Chief.
- Chief: MAX!
- [Max puts his notebook away]
- Maxwell Smart: [In the car, they are about to follow Sontag when 99 suggests they go up to Drago's house] Well what are we gonna tell Drago?
- 99: Tell him that our car broke down.
- Maxwell Smart: Oh come on, 99, he'd never fall for that.
- [the car won't start]
- Maxwell Smart: Come on, let's go up to the house.
- 99: What do we tell Drago?
- Maxwell Smart: That our car broke down.
- 99: What do we do now, Max?
- Maxwell Smart: Well, first of all 99, we've got to look in this coffin.
- 99: Oh... do we have to?
- Maxwell Smart: Well, you see, 99, according to the legend of the vampire, ridiculous though it may seem, Vampires always sleeps in their coffins.
- 99: Why would they do that, Max?
- Maxwell Smart: Well, if you go around biting people on the neck, I guess you'll do just about everything.
- Maxwell Smart: We've got to keep up our cover at all times. We've got to do everything honeymooners do. Here, these pajamas are our best bet. Get into them
- 99: Max!
- Maxwell Smart: They're bullet proof, 99.
