Sorry I don't have YouTube links for all of these.

Seinfeld: George joins a book club, but instead of reading the novel Breakfast at Tiffany's, he attempts to rent the movie: link

Gossip Girl: Blair dreams she is in the final scene of Breakfast at Tiffany's: link

Gilmore Girls (thanks to Nanda for these!)

1. LORELAI: Ooh, it's so good! It's so chock-full of...words like "chock-full." And even if Audrey Hepburn was 20 and Fred Astaire was, like, 80…

CHRISTOPHER: He's still Fred Astaire.

LORELAI: I mean, he could really tap-dance. That was so nice, Chris. That was so romantic and fun and wonderful.

CHRISTOPHER: S'wonderful?

LORELAI: S'Marvelous.

CHRISTOPHER: I'm glad you liked it.

LORELAI: I did. I really liked it.

2. MISS CELINE: You're Audrey Hepburn in Sabrina. Just a waif with eyes.

RORY: Uh, thank you.

RICHARD: Celine, I don't think the handkerchief works with this. Oh, Rory, I didn't know you were here.

MISS CELINE: Richard, look at this girl, what do you see?

RICHARD: Well. . .

MISS CELINE: It's Audrey Hepburn in Sabrina.

RICHARD: Hm, now that you mention it, there is a touch of Audrey in her.

EMILY: But even prettier.

MISS CELINE: Yes, without that ridiculous affected accent. For years I kept telling her, "Audrey, get a speech therapist." She was very stubborn. But could she wear capris.

Glee: Emma sings "I Could Have Danced All Night[/i] while wearing a very Audrey-inspired dress. Here's the song- link and the dress- link

Please add more!

^ Just added them! Thanks! Also, another Gilmore Girls reference (thanks, once again, to Nanda):

LORELAI: Alright first we have to go to Harry's bar and smoke Gauloises cigarettes and get in a fight about cubism and gesticulate wildly.

(what happened to Jo in Funny Face)

link here's another Audrey reference in Gilmore girls (Breakfast at Tiffany's)

my fav is the one where Chris and Lorelai watch Funny Face out of car. so romantic and sweet! ^^.

I can't believe I only saw this now :O
I hate Gossip Girl references...

Glee is so cute! But GG reference was wonderful, I love Lor/Chris watching Funny Face :D

^Sorry for the abundance of Gossip Girl references, lol! It seems that the writers of Gossip Girl and Gilmore Girls have been the most inspired by Audrey. :P

Yes, the scene from Glee is adorable. I wish it were still on YouTube so I could post the link here.

hahaha true (well... Gilmore Girls is inspired by many things). And no problem :)

yes :(

Grr I hate Glee it sucks.

The Gossip Girl connections were hilarious. I loved the one when Blair was walking to Tiffany's and she saw Serena with her minions laughing at her. I also loved it when Vanessa won the Oscar and Blair was saying "I'M AUDREY!" haha :D Oh Blair <3
