Sheldon: I'm H2O intolerant.
[sneezes]

Marlin: It's like he's trying to speak to me, I know it!

Sharks: [reciting] I am a nice, friendly shark. Not a fish-eating monster. Fish are our friends, not food.

Gill: To the top of Mount Wanna-hock-a-loogie!

Dory: What is it with men and asking for directions?

Marlin: Now, what's the one thing we have to remember about the ocean?
Nemo: It's not safe.
Marlin: That's my boy.

Nigel: [quietly] Okay, don't make any sudden moves. Hop inside my mouth... if you want to live.

[About the humpback whale]
Dory: Maybe he only speaks "whale".
[slowly and deeply, imitating the whale]
Dory: Mmmmoooooowaaaaah...
Marlin: Dory. Dory, this is not "whale". You're speaking like "upset stomach".

[Fish farts and bubbles come up by two seagulls. They look at it, then each other]
Seagull 2: Nice.

Marlin: Dory, do you see anything?
Dory: Yeah, I see a light.
Marlin: A light?
Dory: Yeah. I see a light.
Marlin: Yeah, I see it too! It makes me feel happy, which is a big deal for me. Look, it's leaving! I'm gonna get you!
Dory: Come here!
[a big scary fish looms into view]
Marlin: Good feeling's gone, AHH!

Marlin: It's because I like you, I don't want to be with you. It's a complicated emotion.

Dory: I don't wanna forget!
Marlin: I'm sorry Dory, but I do.

Dory: Have you seen a clown fish swim by?
Crab: Yeah, but I'm not telling you, and there's nothing you can do about it!
[Dory holds Crab out of water for the seagulls to see]
Seagulls: Mine! Mine! Mine!
Crab: Okay! Okay! I'll talk!!

Nigel: Hi there. Sorry if I took a snap at you at one time. Fish gotta swim, birds gotta eat.

Gill: Okay, we have 48 hours to make this tank dirty. So I want everyone to think dirty, disgusting thoughts.
[Bloat belches]
Gill: That's the idea!
