Trivia: Phoebe mentions her friend Abby who shaves her head. In a later series of episodes she has a friend named Bonnie who shaves her head, whom she sets up with Ross.
Continuity: When the gang is watching television Ross states, "And that is why evolution is just a theory". However in Season 2's "The One Where Heckles Dies" Ross fights passionately with Phoebe saying that "Evolution is scientific fact, like, like, like the air we breathe, like gravity".
Goof: When Phoebe asks Chandler if he wants to be a chef, Monica says "Hi, there" with her right hand raised. When the camera angle changes, her hand is suddenly on her lap.
Goof: Ross says that the woman he is dating is the curator of insects at the museum. Wouldn't the curator of insects and the curator of moths and other wing-ed things (which is a different woman that he dates in "The One with Russ") be the same thing, since moths are insects?
Continuity: In this episode Chandler says that the WENUS stands for "Weekly Estimated Net Usage Systems". When the WENUS is referred to later in the series, it stands for "Weekly Estimated Net Usage Statistics".
Continuity: Phoebe tells the gang that it was no big deal to her parents when she started walking soon after Ursula. However, in Season 2's "The One with Phoebe's Dad", she tells them that her father left not long after she was born, which means that he wouldn't have been there when she started to walk.
Goof: In this episode the Christmas lights are supposed to be hanging there ever since Christmas, but they are nowhere to be seen in the previous five episodes.
Goof: When Chandler is talking to Joey by the door, the cap on his water bottle changes from on to off between shots.
Goof: When Monica tried to fix the SAP thing on the TV, Phoebe tells her to turn it off. Monica never turns off the TV or even touches the remote, yet the volume of the TV is turned completely off.
Factual Error: When playing Scrabble, Ross tells Phoebe that he doesn't think "scrunchy" is a word. It actually is; defined as "an elastic band covered with gathered fabric, used to fasten the hair, as in a ponytail". It can also be spelled "scrunchie".
Factual Error: Monica and Rachel were attempting to commit insurance fraud. In reality, while checking in all patients must provide ID unless it is an immediate emergency. However, it is the policy of all hospitals that they cannot turn away an obviously injured person regardless of their ability to pay. Rachel would have been treated and the issue of payment dealt with later.
Goof: When Monica says "We both do that," she's pointing at Rachel. When the camera angle changes her hands are on the couch, and in the next shot her hands are in her lap.
Continuity: Phoebe's birthday is inconsistent. In "The One with Frank Jr." Phoebe tells her half-brother that her birthday is February 16th. Also, in this episode, Phoebe has a birthday party in February. However, in "The One Where Nana Dies Twice" Rachel talks about Phoebe's last birthday party. Since Rachel first met Phoebe earlier that season, this implies that Phoebe's birthday must have occurred since September, when Rachel first joined the group. Also, in "The One with Phoebe's Birthday Dinner", Phoebe's birthday is close to Halloween, consistent with Rachel's statement. Furthermore, in "The One Where They All Turn Thirty", the flashbacks of Phoebe's 30th (actually 31st) birthday imply her birthday is in the summer.
Goof: When Monica fills in the form, she uses a pencil with an eraser, yet she stills asks for a new set of papers. She easily could have erased Rachel's info and written hers.
Goof: When Phoebe and Ursula are talking at Riff's, Phoebe's birthday present bag disappears when she moves towards the table. The bag phases out when she gets too close to the split screen that is used when portraying two characters at once.
Goof: Since the producers didn't use real places in the story, they used computer graphics to superimpose fake names on real places. In this episode, they superimposed the name Riff's on some restaurant. During an exterior shot of Riff's at 39:10 on the double episode on the DVD, a man walks in front of the camera and for that split second the name Riff's is superimposed on his head.
Trivia: Here is the translation for the tag scene.
Ross: Aquí está.

Monica: ¿Quién pidió el pollo General Tso?
Translation: Who ordered General Tso's chicken?
Chandler: ¡Pudo haber sido General Tso!
Translation: It might have been General Tso!
Rachel: ¡Miren, miren, el viejo desnudo está haciendo el hula hoop!

All: ¡Hola, Joey!
Translation: Hi, Joey!
Joey: ¡Hola, amigos!
Translation: Hey, everybody!
Monica: Mira, Ross, Marcel se llevó el control remoto.
Translation: Look, Ross, Marcel's got the remote.
Ross: ¡Lo curioso es que no le gusta la tele!
Translation: The funny thing is, he doesn't like TV!
Continuity: For this episode, a larger circular table top has been placed on top of Monica's kitchen table, likely to accommodate the fact that with six players at the table, all the cards, poker chips, food and drinks, the existing table was just too small. The larger top is of a darker wood, but you can see the existing smaller table top in honey-colored wood beneath it. The added top is on the table throughout the entire episode, but is not there in the preceding or following episodes.
Trivia: In the first poker game when Chandler is making his joke about settling the Jamestown colony of Virginia, they use the same reaction shot of Rachel twice. She folds her arms and gives Chandler a "look"; just before and again just after he says, "You see, King George is giving us the land, so...".
