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.
Inspector Gadget: I'm not me anymore. I'm a hardware store.
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.
Penny: This is the coolest watch. It's a radio, computer, and even a phone. Testing, testing. Brain, say something. Come in, Over.
Brain: Brain is not here. Please leave a message at the sound of the woof. Woof.
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.
Penny: Having another hero cop dream, Uncle John?
Officer John Brown: Every time I close my eyes.
Answer: The joke is that he is referring to the "Inspector Gadget" cartoon, in which the Claw never got away with any of his schemes.
