Quotes

 * Baby Kate: But what about D.W.? How could you leave her for three whole days?
 * Nadine: Actually, D.W. hasn't called for me much lately. Even though I'm always there for her when she needs me, I think she might be starting to get too old for me. I hear it happens.
 * Baby Kate: If that does happen, Nadine, you can be my imaginary friend.


 * Baby Kate: A cat, a dog, an imaginary friend. What do these three creatures have in common?
 * Pal: Hair! They all have lots of hair! Am I right?
 * Baby Kate: Pal, I was asking them. (indicates the viewers)
 * Pal: Oh, them. Why were you asking them? They never say anything, even when Arthur talks to them.


 * Baby Kate: D.W. and Nadine have always done everything together. Brush their teeth, play hide-and-seek...
 * D.W.: 8 9 10. Ready or not, here I come.
 * Baby Kate: And Nadine always takes D.W.'s side in an argument.


 * Baby Kate: That hole's big enough. Now we just have to put something in it that we want to grow.
 * Pal: (grabs Mr. Read's wallet) We'll make a wallet tree.
 * Baby Kate: Capital idea.


 * Pal: Good luck finding your fly.
 * Nemo: I already found him. We had lunch. (licks his lips)
 * Pal: Oh! Cats!


 * Nemo: A mouse. Blech. Ugh. It's fake. What a rotten trick.


 * Pal: D'oh. What kind of a creature puts a half-eaten banana in his backpack? (He licks it off his leg.) It's not bad.
