Trivia: In this episode when Rachel asks the group to watch Emma you can clearly see a tan line on her wedding ring finger. Rachel played by Jennifer Aniston was married to Brad Pitt at the time.
Goof: When Ross took Emma's hat off in Central Perk we can hear him saying something, but his lips are not moving.
Magna Doodle: A drawing of an apple with a bullet that's been fired through it
Goof: When Monica and Chandler are on the couch at the coffee house and Chandler says that the adoption people loved the idea of having a child write the letter, we can see his hand on Monica's lower arm. When the camera angle changes to Monica, Chandlers hand is close to her shoulder.
Continuity: Phoebe says she and Mike had their first date, their first kiss, and had sex for the first time all on the same night. Yet their first date was set up by Joey and turned out to be such a disaster that Phoebe left and didn't see Mike again until the next day when he asked her out again. Which means that Phoebe and Mike couldn't possibly have had sex on the night of their actual first date.
Continuity: In this episode Monica says she can't get Chandler to have sex in their bathroom, and he replies that "that's where people go number two." But in "The One After the Super Bowl (2)" Chandler is more than happy to meet Susie Moss, played by Julia Roberts, in a public bathroom when he thinks they're going to have sex.
Rachel: You know, I'm thinking about letting Emma have her first cookie.
Joey: Her first cookie? She has cookies all the time!
Rachel: I've never given her a cookie. Have you?
Joey: No! And for the record, I've also never given her frosting from a can.
Joey: (about writing an adoption recommendation) Alright, lemme see how I'm gonna start... "Dear baby adoption decider people..."
Chandler: So excited about your letter.
Phoebe: Today is Mike and my one year anniversary.
Rachel: Oh! What is the anniversary of? Your first date? Your first kiss? First time you had sex?
Charlie: Y'know, I have a little time if you wanted to... you know...
Ross: Oh... uh, I'd love to, but I really have to grade these papers.
Charlie: Fine, it's fine. I guess I'll just shower by myself.
Ross: (grabs his pen and quickly marks the papers) B, B, B, B, B, B!
Charlie: Ross, you just gave a "B" to a Pottery Barn catalogue.
Ross: Well, it had some good ideas... Take off your shirt!
Ross: (answering the door) Hi Amy!
Amy: You're not Rachel.
Ross: Still sharp as a tack!
Rachel: What are you doing here?
Amy: I have huge news!
Rachel: Oh, sorry. Hold on, let me just check on the baby.
Amy: This is important. Can't Ella wait?
Ross: Her name is Emma.
Amy: Why did you change it? Ella was so much prettier.
Joey: (to Ross, about Amy) She may be the hottest girl I've ever hated.
Rachel: What's your news, Amy?
Amy: Oh! Um... Well, I'm getting married.
Rachel: What? Oh, my God! To who?
Amy: This guy. He has a killer apartment!
Amy: And it's on Fifth. And the elevator opens up right into the living room.
Rachel: No, wh-what's he... what's he like?
Amy: Oh! He's okay... Do you remember my old boyfriend Mark?
Amy: It's his dad.
Rachel: Do you remember Barry?
Amy: Remember him? Hell, we used to make out all the time after you went to sleep.
Rachel: Sometimes just nodding... is okay.
Monica: (about Joey's letter) It doesn't make any sense.
Joey: Of course it does.. it's smart, I used a thesaurus.
Chandler: On every word?
Monica: Okay, what was this sentence originally?
Joey: "They are warm, nice people with big hearts."
Chandler: And that became, "They are humid prepossessing homo sapiens with full aortic pumps"?
Monica: (about his letter) Joey, I don't think we can use this.
Monica: Well, because you signed it, "Baby Kangaroo Tribbiani!"
Joey: (about Amy) We're getting rid of her, right? Rach'... please tell me we're getting rid of her!
Rachel: Joey, I can't do that.
Joey: Oh, come on! Last night I was finishing off a pizza and she said "Oh, oh, oh, a moment on the lips, forever on the hips!" I don't need that kind of talk in my house!
Rachel: Well Joey, um, look, I know that she's difficult, but I think it's really good that she's here.
Joey: 'Cause we'll appreciate it more when she's gone?
Phoebe: I just had the worst anniversary ever.
Chandler: I doubt that! Tell her about us last year.
Monica: Oh, well, I bought Chandler a five hundred dollar watch and he wrote me a rap song.
Chandler: If I were a guy (the gang stares at him) ...Did I just say, "If I were a guy"?
Monica: Maybe you don't need him to propose to you, maybe you can propose to him.
Phoebe: Oh, I don't know. I don't know, isn't that a little... desperate?
Monica: I proposed to Chandler! (after an awkward moment) ...Alright, moving on...
Amy: (to Rachel) Nana's on the phone.
Rachel: Oh! That's interesting, since she died seven years ago.
Amy: She did? Who got her condo in Boca?
Ross: (about their nanny being sick) Did Molly say what she had? ...because my throat's been hurting.
Rachel: Menstrual cramps.
Ross: I don't think that's what this is.
Ross: (about Amy) I do not want her babysitting our child.
Rachel: Why not?
Ross: Well, for one thing, she keeps calling her Ella!
Rachel: Well, Ella's a nice name...
Ross: Fine, we'll call the next one Ella!
Rachel: What? The next one?!
Monica: (about Joey's handwritten adoption letter) We're screwed, aren't we?
Chandler: They loved it!
Chandler: Yeah. They thought it was very smart of us to have a child write the recommendation letter.
Monica: They thought Joey was a child?
Chandler: She guessed eight or nine... based on his drawings.
Rachel: (about Emma) You pierced her ears?
Amy: Doesn't it make her nose look smaller?
Rachel: How could you do this without telling me?!
Amy: Well, if I had told you, then it wouldn't have been a surprise, now would it?
Chandler: I think she looks cute. (Rachel and Monica give him a look) ...But I am wrong.
Amy: Hey, y'know what? This kid needs me, okay? ...she needs to have a cool, fun aunt!
Monica: I'm a cool, fun aunt!
Amy: (being magnanimous) Okay...
Chandler: Hey! Monica can be cool and fun at organized indoor projects.
Rachel: I can't believe this! All I wanted to do was help you try and figure out what to do with your life, and this is how you repay me?!
Amy: Well I don't need your help, because I already know what I'm going to do with my life.
Rachel: Oh, yeah? Since when?
Amy: Since today! I am going to be a baby stylist!
Rachel: (incredulous) What?
Ross: That's not a thing!
Amy: Well, it should be! I'm going to help babies learn how to accessorize, what colors to wear, what clothes are slimming...
Rachel: Babies don't care if they're slim!
Amy: Enter Amy!
Ross: Amy, I just, I just want to...
Amy: What? What are you gonna do?
Ross: No more falafel for you!!
Amy: You know what? Ever since I got here, you have been nothing but negative.
Rachel: Excuse me?
Amy: You didn't want me to marry the old guy with the great apartment. Then I tried to help your daughter to (pointing emphatically at her own nose) de-emphasi-ize her fuh-laaaws! And suddenly I'm the bad guy?
Mike: Phoebe, I love you. There's no one else in the world I would ask to marry me... three times. But, I wanna take care of you, have babies with you, and grow old with you... Phoebe Buffay, will you marry me?
Phoebe: (beaming) Yes!
