- Grandpa Little: [waiting for Dinky's glider to take off] Get going, Dinky!
- Dinky Little: Roger! Pilot to navigator: check wind velocity, watch out for birds, chart the course, look out for television antennas, advise me of altitude...
- Grandpa Little: Navigator to pilot: SHUT UP!
- Tom Little: [referring to Augustus] His voice gives me the creeps; I wonder what he looks like.
- Lucy Little: He's probably 20 feet tall, with beady eyes and long, pointy fangs for teeth!
- Tom Little: [sarcastically] You're real fun to be with, Lucy.
- Lucy Little: [hugging/kissing Tom with relief, after he escapes being hurt while attempting to extract a piece of cheese from a mousetrap] Oh, you could have gotten yourself killed! I'm very angry at you, Thomas Little!
- Tom Little: You're angry at me, and you're hugging and kissing me? I'll never understand girls!
- Grandpa Little: Can't you make this crate go any faster?
- Dinky Little: Don't tell me how to fly; I'm the world's greatest pilot! I can tell you...
- Grandpa Little: [ties Dinky's scarf over his mouth] Shut up!
- Grandpa Little: [as glider spins out of control] Watch out, fool!
- Grandpa Little: [falling from the plane] You are the world's greatest knucklehead!
- Grandpa Little: [after the pair are spotted by Augustus, who has mistaken them for toys] Good, he thinks we're toys. Pretend you're a toy!
- Dinky Little: First I'm a mouse, then bait, now a toy? I never live it down!
- Grandpa Little: You cabbage-head! If Augustus finds out who we are, there's no telling what he might do to us!
- Dinky Little: I'm a toy! I'm a toy!
- Grandpa Little: [after Dinky has fainted when he and Grandpa are nearly cut to pieces by a lawnmower] Dinky? Wake up, Dinky!
- Dinky Little: [groggily, after coming to] Are we in heaven?
- Grandpa Little: I should hope not; I wouldn't want to spend eternity with you!
- Henry Bigg: [having spotted Grandpa and Dinky while mowing the lawn] What are those?
- [picks them up]
- Henry Bigg: What weird little things!
- Dinky Little: [offended] Who's a "weird little thing"? I...
- Grandpa Little: [covers Dinky's mouth] Shhhh!
- Grandpa Little: [preparing to lower himself into Augustus' chimney from Dinky's glider, via a rope] When the crows leave, land on the roof, and we'll meet you there. Keep the glider steady, and put me in that chimney!
- Grandpa Little: [after smacking into the outside chimney wall] I said put me in the chimney, not in the hospital!
- Lucy Little: Watch it! Don't fall in!
- Tom Little: I never fall; I've got perfect balance!
- [yells as he loses his balance and fails into Henry's suitcase, which he had been sitting on the edge of]
- Lucy Little: Tom!
- Tom Little: Get me out of here!
- Lucy Little: [sarcastically] Who could that be calling? It couldn't be my brother, he's got perfect balance!
- Tom Little: Will you stop clowning around and give me a hand?
- Dinky Little: [looking around Augustus' attic for Tom, Lucy and Grandpa] Kids? M-Mr. Little?
- Tom Little, Lucy Little: [emerging from a trapdoor] Hi, Dinky!
- Dinky Little: [jumps back, yells out with fright, then calms down] Hi, kids. I was just exploring this old place. You know how Daredevil Dinky loves adventure!
- Dinky Little: [adjusts his scarf, which gets caught on a nail, cries out] Aaah! Something's grabbing me!
- Lucy Little: [dislodging Dinky's scarf] It's just this ferocious nail.
- Lucy Little: [crying, thinking Tom has been swallowed by a cat] Oh, Tom, what'll I do without you? You're the best brother a girl ever had! Kind and good and brave...
- Tom Little: [emerging suddenly from atop the cat's back] And smart!
- Lucy Little: Tom!
- [hugs Tom with relief as he climbs down and runs to her]
- Lucy Little: And stupid for letting us think you were swallowed!
- Grandpa Little: [tapping his hand against the bulldozer, which has just stopped inches away from destroying the Littles' home, ostensibly by Dinky throwing himself in front of it] It stopped!
- Helen Little: That was a brave thing to do, Dinky!
- Grandpa Little: Sure was. If there's anything I can ever do for you, name it!
- Dinky Little: [sounding lightheaded] There is one thing: you can catch me while I faint!
- [cries out, falls backwards, landing in Grandpa's arms]
- Uncle Augustus: Stop that sniffling and carry your miserable things upstairs!
- Henry Bigg: Yes, sir.
- Uncle Augustus: Stop dawdling. Life isn't going to be soft for you, like it used to be. I'm your guardian now!
- Uncle Augustus: [to a stray cat, which has found its way into the house] Get out of here, you mangy animal!
- Henry Bigg: [picking up the cat as it runs towards him] Hi, kitty. Can I keep him, Uncle? Please?
- Uncle Augustus: I don't need another mouth to feed!
- Henry Bigg: But he'll get rid of the mice for you.
- Uncle Augustus: [thinking it over] The mice? Hmmm... very well. But that mangy creature's not here for you to play with; it's here to work!
- Lucy Little: [after she and Tom are reunited with Grandpa and Dinky, who have just escaped from being locked inside Augustus' desk] Grandpa, Dinky! Are you OK?
- Grandpa Little: Yeah. Good you're here. Quick, we have to get home! Did you hear that Augustus?
- Dinky Little: [referring to Henry's gas-powered toy plane, which was damaged by an owl earlier that night] Then let's find that airplane and see if we can repair it!
- Grandpa Little: Well, congratulations, Dinky. You finally said something intelligent!
- Tom Little, Lucy Little: [spotting Grandpa landing in Augustus' house, after plunging down the chimney] Grandpa!
- Grandpa Little: [hugging Tom and Lucy] Thank goodness you're OK!
- Lucy Little: Yes, but Mom and Dad won't be unless we can get home in time to warn them.
- Tom Little: In two days, Augustus is gonna send bulldozers to tear down Henry's house.
- Grandpa Little: You are a heartless, vicious old man, Augustus!
- Lucy Little: Not only that, but he also slurps his soup.
- Dinky Little: [seeing his glider being torn to pieces by a cat] My glider!
- Tom Little: A cat!
- Lucy Little: How are we gonna get home in time now?
- Tom Little: I know! Dinky can tame the cat, and we can ride home on his back!
- Dinky Little: [shocked by the suggestion] Huh?
- Tom Little: Didn't you once tell me you were a lion tamer?
- Dinky Little: Of course. The greatest! But I can't tame that cat; I need special equipment that I don't happen to have.
- Grandpa Little: [disgusted] Such as courage.
- Lucy Little: This is fun, like a potato sack race.
- Tom Little: If Augustus sees us, we'll be mashed potatoes!
