Gilbert: [climbing of the water tower] It's not going to happen again. This is the last time. Right Arnie? Arnie: It's the last time. Gilbert: Okay. Let's go. Arnie: But I want to go back up there again.
Arnie: Match in the gas tank, *boom* *boom*!
Arnie: I'm having a birthday party, but you're not invited, but you can come if you want.
Becky: Tell me what you want, as fast as it comes to you. Gilbert: Uhh... Becky: Okay? Gilbert: 'Kay. Becky: Okay. What do you want? [He's thinking about it] Becky: Faster! Gilbert: Okay. I want a new thing. House. I want a new house. And a family. [...
[Arnie jumps onto Gilbert's back] Gilbert: God, Arnie, you're getting so big. Pretty soon I ain't gonna be able to carry you no more. Arnie Grape: No, you're getting littler, Gilbert. You're getting littler, you're shrinking! You're shrinking, Gilber...
Becky: I love the sky. It's so limitless. Gilbert: It is big. It's very big. Becky: Big doesn't even sum it up, right? That word big is so small.
Momma: You're my knight in shimmering armor. Did you know that? Gilbert: I think you mean shining. Momma: No shimmering. You shimmer, and you glow.
Arnie Grape: Good night to you but not me.
Gilbert: Why will I take care of it? Arnie: Gilbert... Gilbert: Hmm? Arnie: 'Cause you're Gilbert. Gilbert: 'Cause I'm Gilbert.
Momma: [meeting for the first time] Hello. Becky: Hi. Momma: I haven't always been like this. Becky: Well, I haven't always been like this, either.
Gilbert: You know what? You're such a big boy. Arnie: Yeah! Gilbert: You're such a big boy. Arnie: I'm a big boy! Gilbert: You know what? I bet you could do this all by yourself if you really wanted to. Could you do this by yourself? Arnie: I'm a big...
Gilbert: [to Becky] I don't know what to say. Arnie: Say "thank you," Gilbert. "Thank you." Gilbert: [whispering] Thank you.
Gilbert: You don't hurt Arnie, you just don't.
Gilbert: I'm not gonna let her be a joke.
Gilbert: We don't really move. I mean, we'd like to, but... my mom is sort of attached to the house. Attached is, I guess, not the right word. She's pretty much wedged in.
Tucker: How's momma? Gilbert: She's fat. Tucker: Come on, man. She's not all that big, Gilbert. Gilbert: What? Tucker: Listen, I saw a guy at the state fair who was... a little bit bigger. Gilbert: A little bit bigger? Tucker: Look, all I'm sayin' is...
Arnie Grape: I could go at any time.
Arnie: We're not going anywhere! We're not going anywhere! Arnie: [looks at Gilbert in the truck] Where're you going?
