- David Seville: Theodore... Simon... Al-vin!
- Alvin, Simon, Theodore: Yes, David dear?
- David Seville: I am fully aware that there are only five more days before Christmas, and 370 days until next Christmas!
- Alvin: Ladies and gentlemen, I want you to meet a very special friend of mine. He's come a long way to help us celebrate the best Christmas Eve ever!
- David Seville: [coming up to the boys' room] Maybe I was a little hard on Alvin. I think I'll tell him that I...
- Alvin: [panicky, still in his sleep] Money! I need money!
- David Seville: [heading back downstairs] I give up.
- Mrs. Claus: Well, how did it go, darling?
- Santa Claus: Oh, just fine, sweetheart, just fine. You know, you ought to get out some Christmas and see how the rest of the world lives.
- Mrs. Claus: Oh, I don't know. Making children happy is your job. Perhaps I'm just an old homebody.
- [after Alvin sings "The Chipmunk Song" with Simon and Theodore, but out of tune]
- David Seville: Well?
- Alvin: I'll tell you what, Dave, let's take a break.
- David Seville: Take a break?
- Alvin: Gee, thanks, Dave!
- [he zips away]
- David Seville: Al-vin!
- David Seville: [just discovering the boys, dressed as Santa and his elves and taking pictures with all the neighborhood children, in hopes of raising money to buy Alvin's new Echo harmonica] What's all this?
- Simon: We're helping Alvin make money.
- David Seville: Al-vin!
- Alvin: My name's not Alvin, it's Santa.
- David Seville: [advancing toward Alvin] All right, Santa, I'd like a word with you and your elves!
- Alvin: I'm sorry, but you'll have to wait in line like everybody else.
- David Seville: Now just a minute...
- David Seville: [reciting his Christmas poem, "The Spirit of Christmas", which he wrote several years ago] Yes, Christmas, Christmas, Christmas time, a giving, giving, giving time, so let's all give a cheer for...
- Alvin, Simon, Theodore: Money!
- David Seville: [after Alvin plays "Silent Night" on his new echo harmonica at the department store] Alvin, I owe you an apology. That was a wonderful thing you did for Tommy.
- Alvin: That's okay. Where'd she go?
- David Seville: Where did who go? I don't see any...
- Alvin: The nice lady who gave me the harmonica for Christmas. She just disappeared.
- Theodore: Dave, we'd better get going.
- Simon: We don't want to be late for Carnegie Hall.
- David Seville: And we have a surprise for you when we get there, Alvin.
- David Seville: [after Alvin gets his harmonica, which he forgot] You see, Alvin, it's your responsibility to...
- Alvin: Right, Dave. Responsibility. We'll share some responsibility. You go on and get the studio ready, while we go window shopping.
- David Seville: Well, that sounds fair enough.
- [calling after the boys, skating on their skateboard to the department store]
- David Seville: Hey! Don't be late!
- Alvin: [as he, Simon, Theodore, and Dave are on their way to their recording session] Working on Christmas vacation is criminal!
- David Seville: Aw, come on, you guys. It's only a little recording session.
- Alvin: It's work!
- David Seville: Maybe I'll let you play your harmonica, Alvin.
- Alvin: My harmonica!
- David Seville: I say it's about time we remember how lucky we all are, and think about the *real* meaning of Christmas. You remember that poem I wrote a few years ago, "The Spirit of Christmas"?
- Alvin: Oh no, Dave.
- Theodore: Not that again!
- Simon: Honest, Dave, we remember it *very* well.
- [he and the others duck behind their Christmas tree]
- Simon: We still don't know what to do about Carnegie Hall.
- Clyde Crashcup: I have begun with Santi Claus. That's 'Santi' for 'Santi', and 'Claus' for 'Claus'. Santi Claus. A kind man with a beard, and - a hat.
- Alvin: [uttered slowly in his sleep, before he starts dreaming about his trip to visit Clyde Crashcup] How can you play a harmonica at Carnegie Hall if you don't have a harmonica? So I've gotta have moneyyy, moneyyy, moneyyy, moneyyy...!
