Dory: Hey there, Mr. Grumpy Gills. When life gets you down do you wanna know what you've gotta do?
Marlin: No I don't wanna know.
Dory: [singing] Just keep swimming. Just keep swimming. Just keep swimming, swimming, swimming. What do we do? We swim, swim.
Marlin: Dory, no singing.
Dory: [continuing] Ha, ha, ha, ha, ho. I love to swim. When you want to swim you want to swim.
Marlin: Now I'm stuck with that song… Now it's in my head.
