- Penny: Uncle Gadget, are you alright?
- Inspector Gadget: Of course, I'm alright. A good detective is always on his nose - uh, I mean toes.
- Ring Master: Dr. Claw wants Gadget eliminated!
- M.A.D. Clown: Don't worry. I filled the car up with rocket fuel! It'll hit him so hard, he'll end up in orbit!
- [both chuckle evilly]
- [Gadget and Penny are standing next to a cage, before Gadget's second performance: an animal act featuring a lion called Brutus]
- Inspector Gadget: It's like I always say, Penny: If you can't lick 'em, join 'em. Then lick 'em.
- [Brutus then licks Gadget's face]
- Inspector Gadget: [standing on a trapeze platform] Wowsers! Didn't look this high from down there. At least they have a safety net. Better safe than sorry, that's what I always say.
- Dr. Claw: Curses! Gadget has uncovered our undercover operation! But no one will ever uncover me, or M.A.D. Cat!
- Inspector Gadget: [to an elephant] Do you know you're blocking a public thoroughfare? I insist you remove yourself immediately. If you don't, I'll see you in traffic court.
- [the elephant drinks water out of the bucket]
- Inspector Gadget: Okay! You had your warning!
- [cuffs the elephant's trunk]
- Inspector Gadget: I'm running you in!
- Inspector Gadget: Well, what do you think of my disguise, Penny? The ring master gave me the job. Told you, eh?
- Penny: You sure did, but your shoes are on the wrong feet.
- Inspector Gadget: That's all part of it, Penny. Let those M.A.D agents think I'm a foolish clown, and before long, they'll be laughing on the other side of their faces.
- [laughs]
- Penny: Good idea, Uncle Gadget. They'll never suspect a clown that's just hanging around.
- Inspector Gadget: I'd like to apply for another circus job. I'll take anything.
- Ring Master: What a coincendence. I was coming to see you about filling in for one of our trapeze artists.
- Inspector Gadget: What's wrong with him?
- Ring Master: Oh, just a little cold.
- Inspector Gadget: Wow, must get pretty draughty up there on those swings.
- Inspector Gadget: [sees Chief Quimby hiding in a popcorn machine] Chief Quimby! When did you run away to join the circus?
- Inspector Gadget: [standing on a raised platform, about to perform an extremely high dive into a bucket of water] Why, the chances of surviving a fall from this height must be one in a zillion! That is, if it wasn't for my trusty Gadget 'brella!
- [first lines]
- Penny: Wow, Uncle Gadget! Why didn't you tell me we were going to the circus?
- Inspector Gadget: I thought I'd surprise you, Penny. I have a little top secret business to take care of here, but it shouldn't take all day.
- Inspector Gadget: By the way, what happened to the clown I'm replacing?
- Ring Master: Er, um, uh, he... he caught a cold. I really appreciate you're filling in for him. You say you've had circus experience.
- Inspector Gadget: I've seen enough of them to know what I'm doing.
- [Gadget, Brain, and two of The Flying Zucchinis, the trapeze artists, are falling after the M.A.D Clown has cut the ropes]
- Inspector Gadget: Wowsers! Something tells me this was a trap trapeze!
- Inspector Gadget: [after seeing Dr.Claw's M.A.D. Jet pass by] Mmm. I'm gonna call the airport. That plane has a real dirty engine.
- [Penny is snooping around looking for clues, when the ring master suddenly appears]
- Ring Master: Hey! What are you doing there?
- Penny: Uh... I'm looking for the clown's trailer. One of them's a friend of mine and uh...
- Ring Master: Well, that's not it! The clown's trailer is over there!
- [points to where the clown's trailer is]
- Penny: Thank you very much, sir.
- Dr. Claw: Three times you have tried to dispose of Gadget! Three times you have failed! You have one last chance!
- Ring Master: Oh, thank you, Dr. Claw.
- [pulls out a rag to wipe the sweat off his face]
- Ring Master: I guarantee that this will be Gadget's final performance!
- Inspector Gadget: But, Chief. What would M.A.D agents want to steal from a circus?
- Chief Quimby: No, no. They disguise themselves as circus performers and do Dr. Claw's dirty work anywhere the circus stops.
