Trivia: When Rachel and Amy are in Rachel's bedroom talking, you can see that where the door was sawed through by Joey, there is still the old hinge just above the division, but they've also added a hinge directly below it. Without this additional hinge on the bottom section, it would just flop around rather than swing open smoothly as a separate mini-door.
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's where people make 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.
Trivia: Rachel says that the cake she ordered for Emma's birthday contains nuts. Although necessary for the "nuts" joke, you would never put nuts in a one year-old's cake. Their molars, necessary for properly masticating nuts, don't usually arrive until their second year. Nuts may also present problems as a choking hazard or with possible allergic reactions.
Continuity: Emma was born in May for the Season 8 finale, however, in this episode, her birthday is celebrated in October. What's more, if you consider the fact that she was conceived in mid-April of 2001--one month before Chandler and Monica's wedding--her first birthday should have been the previous January, nine months earlier.
Continuity: In "The One Where Rachel Has a Baby (2)", Phoebe and Ross are looking into the nursery as Emma is brought in by one of the nurses. The card on her baby capsule reads "Emma Geller-Greene". Whereas, in this episode, the cake box that Ross brings in is labelled "Green".
Continuity: When Estelle tells Joey he needs a monologue for his audition, he says he doesn't have a monologue prepared. But in "The One in Barbados (1)", Joey says that he memorized a monologue from Star Wars for an audition.
Goof: At Emma's first birthday, her half-brother Ben and her maternal grandparents and aunts are not in attendance. If the party was for people that were close to Emma and her family, why wasn't anyone from Rachel's family there?
Goof: When Joey asked Jack and Judy Geller if their gift to Emma could be from all three of them, Jack asked Joey "Which one are you?" However, there are only three men in the Friends "group." Ross is Jack's son, and Chandler is his son-in-law (and Jack has known Chandler for years since he was Ross's college roommate). So with whom was Jack confusing Joey?
Phoebe's Song: "Emma"
Emma, your name poses a dilemma,
'Cause not much else rhymes with Emma.
Maybe the actor Richard Crenna,
--he played the commanding officer in Rambo.
Happy Birthday Emma!
Magna Doodle: Happy, happy 1
Goof: Phoebe is the only one who is not asked to record a message to Emma for her 18th birthday video.
Continuity: How is Ross's tan from the previous episode gone? It doesn't go away that quickly.
Continuity: There are a number of references to the fact that Rachel couldn't stop laughing when Ross first kissed her, but that isn't true. In "The One Where Ross and Rachel... You Know", she said she was laughing because, "Whoa! Ross's hands are on my butt!" The "kissing" had been fine up to that point.
Goof: Ross was instructed that after his front was sprayed, he should count to five, pat himself down to avoid drips, then turn. By the time he reached "...three Mississippi", the spray started again. In other words, even if he hadn't counted using "Mississippi", he still wouldn't have had time to pat himself down and turn before the second spray.
