- Inspector Gadget: You blew me up and my Chevette. And I really liked that car.
- Dr. Claw: Well, you crushed my hand and I really liked that hand. So Go-Go get over it!
- Bewildered Japanese Tourist: [as Robo Gadget is attacking the city in a Godzilla-like fashion; in English subtitles] This is why I left Tokyo!
- Dr. Brenda Bradford: Two things, Scolex! One, you are completely insane!
- [Claw shrugs]
- Dr. Brenda Bradford: And two, I liked you better fat!
- [Claw is shocked. His cat hides...]
- Dr. Claw: BRING ON THE BROWNIES! WHEEL IN THE WAFFLES! I'M READY TO BINGE! Ha-ha-ha!
- Inspector Gadget: I don't know what you're up to, Scolex, but you'll never get away with it!
- Dr. Claw: Oh, how cliché, Inspector. I think somebody's been watching too many Saturday morning cartoons.
- [Dr. Claw, Kramer and Inspector Gadget look at the camera]
- Gadgetmobile: Who are you, rookie?
- Inspector Gadget: I'm Officer John Brown, and you're exceeding the speed limit.
- Gadgetmobile: Speed limits are for cars, not the Gadgetmobile.
- Inspector Gadget: Are you - Are you talking to me?
- Gadgetmobile: Speaking of breaking the law, who's not wearing a seat belt? You gotta wear the belt, baby. It's a Disney movie.
- Scolex: Why, it's that annoying little security guard from the institute. So he's the lucky duck they plucked for the Gadget Program. Heh! Irony bounds.
- Inspector Gadget: I don't get it. Why would you do this?
- Dr. Claw: I'll tell you why. To make techno-warriors that never get tired, never get hungry, and never say "no". Every army in the world would be made up of my creations. Imagine the confusion, Gadget, huh? Imagine the perks. COMPRENDÉ?
- Inspector Gadget: Yeah, I comprendé.
- Dr. Claw: No-no-no-no-no-no-no-no. I comprendo, yo comprendo. Conjugate the word, for pity's sake.
- Gadgetmobile: Better buckle up, Penny. This car's only got two speeds: "Fast" and "WOW! What Was That?"
- Gadgetmobile: Let's team up: I'll go after them; and you say 10-4!
- Inspector Gadget: 10-4?
- Gadgetmobile: Right. See ya!
- [speeds off after some escaped convicts, leaving Gadget just standing there]
- Dr. Claw: [after being defeated by Inspector Gadget] Arrivederci, Gadget! This is NOT goodbye. I'll get you next time, Gadget! I'll get you!
- Officer John Brown: Thelma, how do I look?
- Thelma: Like a geek from Kansas who became a security guard.
- Officer John Brown: Dr. Bradford? Hi. I borrowed a book from your dad. "Power Learning Through Speed Study." It took me forever to get through it.
- Officer John Brown: Attention: Driver of the wrecked limo attached to the "Yahoo!" billboard, this is security officer John Brown. Please step out of the vehicle immediately, or... else.
- Scolex: [stepping out, unable to give in without a fight] Fine work, Mr. Security Guard, you got me. Here, have a victory cigar.
- [pulls out a cigar and lights it...]
- Officer John Brown: No, thanks.
- Scolex: Remember: Smoking kills.
- [tosses cigar]
- Officer John Brown: I don't smoke!
- Scolex: [laughs] Oh, really? You will now.
- Officer John Brown: Oh, boy...
- [the cigar blows up John; also sending a bowling ball rocketing out of John's car. Scolex closes his sunroof, but the bowling ball falls through the sunroof before closing, and crushes his left hand]
- Scolex: AAAAAAAAAAAAAAH! MY HAND!
- [at Scolex Industries]
- Gadgetmobile: Can you find the Scolex Building from here, or should I call the police?
- Inspector Gadget: I am the police!
- Penny: Hey, wait! What about me?
- Gadgetmobile: You're smarter than he is. Stay in the car.
- Robo-Brenda: I look just like you! Only prettier... hey, I bet we even share brain waves! Are you thinking about Gelato? Cause I am!
- Dr. Brenda Bradford: OK... I'm going to go find John.
- [walks away]
- Robo-Brenda: Aw, well, don't you wanna hang out?
- Dr. Brenda Bradford: I'll be with you every step of the way!
- Inspector Gadget: Okay. I'd shake your hand, but you might lose an eye.
- Gadgetmobile: [two guys are trying to steal a Dodge Viper but Inspector Gadget doesn't notice that they are actually ecaped convicts and this upsets the Gadgetmobile] That's it. I can't take this anymore. Step away from the Viper!
- [during the credits, RoboBrenda is doing an exercise show that only she can do, as she is spinning seemingly uncontrollably]
- Robo-Brenda: And kick, and kick and kick and kick and kick and kick and fall!
- [RoboBrenda falls off the deck onto the beach which isn't too far down]
- Scolex: Hello. Sanford Scolex. We were at Harvard together.
- Dr. Brenda Bradford: We were?
- Scolex: Oh, you don't recognize me. That's because I've changed. I was obese. Maybe you remember me like this.
- [fills his mouth with air to simulate his prior obesity]
- Mayor Wilson: Dr. Bradford both I and Police Chief Quimby here are very sorry to hear about your father. He was a good man!
- Dr. Brenda Bradford: Oh did you know him?
- Mayor Wilson: No! I didn't!
- Dr. Brenda Bradford: [gives her an odd look]
