Lois: Dewey, your father and I are so proud of the way you've taken care of that fish.
Hal: Yes, we are. You've certainly proved to us you can be trusted.
Lois: It's so nice to have a boy who's so conscientious, responsible and honest and who finds a way to do the right thing. Before we go any further, is there anything you wanna tell me?
Dewey: I want a beagle!
Lois: Well, you're not gonna get it, you little sneak!
Hal: We know you've been switching fish, 'cause I put a dead fish in there last night!
Dewey: That's cheating! You're cheaters! [sobs and runs out]
Hal: It's not exactly textbook but at least we're not getting a dog.
