Goof: Monica says she has Rachel's mom's number in her book and that she would call her. However, she doesn't use her book. She dials the number as if she has it memorized.
Trivia: Rachel says her nanny taught her to say "Tu madre es loca," which is Spanish for "Your mother is crazy."
Goof: At the end of the episode when Ross is telling Rachel that she will be a great mother, he leans forward and puts his hands on her legs while Rachel is sitting upright. When the camera angle changes, Rachel is leaning back in the cushions with her hands on her belly and Ross's hands are not on her legs.
Goof: At the end of the episode, a blue-green mat can be seen in the background after Monica falls and bites her tongue.
Monica: Both your sisters called... neither one can make it.
Rachel: What? You mean they can't come to a social event where there's no booze or men? That's shocking!
Rachel: My mom's not gonna be here?
Monica: Well, given that we forgot to invite her it would be an awfully big coincidence if she was.
Rachel: My God!
Monica: Well, it wasn't my fault, Phoebe was in charge of the invitations.
Phoebe: Well, I don't, I don't have a mother, so often I forget that other people--
Monica: Oh, give it a rest!
Rachel: So, my mother is not coming to my baby shower?
Phoebe: No... Neither is mine.
Phoebe: (to Mrs. Green) I'm so glad you could make it.
Monica: Yes, thank you so much. And again, we're so sorry. We could not feel worse about it.
Mrs. Green: Try.
Mrs. Green: (to Rachel) Oh, look at that face, just like when you were in high school. If I didn't know better, I'd swear you were a cheerleader in trouble.
(Ross and Chandler are pretending to be contestants on "Bamboozle" for Joey)
Joey: Our first contestant is Ross Geller. Why don't you tell us a little bit about yourself, Ross.
Ross: Well, I'm a paleontologist. I live in New York. I have a son, Ben... (waves) Hi, Ben! And--
Joey: I said, a little bit, Ross. Now, how about you Chandler.
Chandler: Well, Joey, I'm a headhunter. I hook up out-of-work Soviet scientists with rogue Third World nations. (waves) Hi, Rasputin!
Mrs. Green: Sweetheart, I know you're gonna be a terrific mom, I just think you need a little help--especially at the beginning...
Rachel: But mom, I really know what I'm doing... I can handle this.
Mrs. Green: Really? Remember Twinkles?
Rachel: He was a hamster! I am not going to vacuum up my baby!
Rachel: Why did you invite my mother?
Rachel: She wants to move in with me and Ross to help take care of the baby.
Phoebe: For how long?
Rachel: Eight weeks. I mean I love my mother, but my God, a long lunch with her is taxing.
Monica: I personally would be honored if she wanted to live with me.
Phoebe: She can't hear you.
Joey: Now, Chandler... would you like to spin the Wheel of Mayhem or pick a Wicked Wango card?
Chandler: Ahhh, let me think... I don't care.
Joey: You must choose, Mr. Bing.
Chandler: Either... it doesn't matter.
Joey: Choose... you jackass!
Rachel: (referring to her unborn baby) It goes ten times a day?! What are we feeding this baby? Indian food?
Ross: (entering Monica's apartment, out of breath and flushed) Hey!
Phoebe: Why are you all red and sweaty?
Ross: I just bamboozled Chandler! (seeing the girls all staring at him) ...which is not a sexual thing.
Ross: Well, I'm not like Rachel's dad... and no offense, but he's an ass!
Mrs. Green: I knew I liked you, Ross!
Ross: Look, I have a son... and his mother and I didn't live together, and whenever he was with me I took care of him all the time, by myself.
Mrs. Green: That's true, you do have another child.
Mrs. Green: With another woman. Have you no control, Ross?
Ross: That's a different issue...?
Ross: Look, y'know when you first came to the city? You were this spoiled helpless little girl who still used daddy's credit card. Do you remember?
Rachel: I hope you're going somewhere with this.
Ross: Look at you! You're, you're this big executive! You are much more capable than you give yourself credit for. I have no doubt you're gonna be an incredible mother.
Ross: I'm telling you.
Rachel: (moved) Thank-you.
