Inspector Gadget: All work and no play makes Gadget a dull boy.
Inspector Gadget: [whilst bouncing a basketball] They say the hand is quicker than the eye, but the Gadget hand is even quicker.
Inspector Gadget: [about to hit a punching bag] Float like a butterfly, sting like a bee! That was my motto!
[Gadget misses the punching bag and hits himself in the face]
Inspector Gadget: [giddily] Or was it the other way around?
[Gadget is being followed by Brain on a scooter, but Gadget thinks he is a M.A.D agent, and so does everything he can to shake him off. Eventually, he manages to do so, by using the oil slick]
Inspector Gadget: This may help you get a grip on things!
[Brain slips on the oil, looses control of his scooter, and ends up in the lake]
Inspector Gadget: [about to have a steam bath] A little steam keeps you on the beam! That's what I always say.
Chief Quimby: [sighs with relief] At last, an assignment that didn't blow up in my face!
[Gadget is jogging to work]
Inspector Gadget: I should jog to work every morning.
Inspector Gadget: [referring to his body] This body is a finely tuned instrument, capable of amazing feats of strength.
Penny: But, Uncle Gadget. I don't remember you entering any contest.
Inspector Gadget: That's the beauty of these modern lotteries, Penny. Everyone gets a chance. They probably just drew my name out of a hat.
Inspector Gadget: I could exercise my gadgets. But Dr. Claw lets me do that all the time.
Chief Quimby: Even when you're on vacation, you're still on duty.
Inspector Gadget: Chief! I'm always on duty!
Penny: And we're glad you are, Uncle Gadget.
Madamé: [to Gadget, of whom has just arrived at the Bide-A-Wee health spa] We're completely at your service. You're our only guest at the moment, so you'll be getting special treatment.
Madamé: [after finding out about Gadget discovering her torture chamber, although Gadget is unaware of this] So, Gadget has found my torture chamber. Finishing him off for good should be easy.
[Penny has been caught by a M.A.D agent, is struggling to get free, and then bites him on the finger. Dr. Claw then orders the agent to lock Penny in the basement]
Madamé: [to the M.A.D agent] Lock her in the basement!
Dr. Claw: I give the orders!
Madamé: [nervously] My apologies, Dr. Claw.
Penny: Dr. Claw!
