Trivia: Joey's cologne-selling job is at Saks Fifth Avenue.
Goof: Chandler dials Janice's number from memory, but since he last saw her she got married. It's unlikely that she would still be reachable at her old single-woman number in her new home. If the phone she'd answered had been a cellphone, it might have made sense, but the phone she answers is clearly a land-line.
Trivia: The giant magnifying glass that Joey ultimately ends up with was a device sold in the 40's and early 50's to allow cheaper televisions--some with only 3", 5" or 7" screens--to have a more viewable picture area. With the introduction of more affordable large-screen televisions in the mid-50's, they were discontinued.
Goof: Mr. Heckles' apartment in this episode definitely doesn't seem to be located directly underneath Monica and Rachel's, and also is not the same apartment as shown in previous episodes.
Goof: In the scene when Ross and Phoebe are talking about evolution and Phoebe tells him that he believes in something and she doesn't, she turns and she's asking "Why not?" but her lips are not moving.
Goof: In the scene where the gang is at Mr. Heckles' apartment, Ross tries to explain evolution to Phoebe with bird models. At one point he drops the first bird but when the camera angle changes, the model is still there.
Factual Error: In the scene where Joey tells the gang that he used to date a girl with a big Adam's apple, they all tell him that "women don't have Adam's apples." Actually, women do have Adam's apples. Everybody does, however, in women, they aren't as large or as apparent, due to less cartilage protruding.
Note: Although it is obviously true that women have cartilage in their throats, it is the "protruding" cartilage, only found in men, that the term "Adam's apple" refers to, not the cartilage itself. Therefore, the statement, "Women don't have Adam's apples" is correct.
Goof: When the gang is in Heckles's apartment and the door is open, you can see there is a door at the end of the hallway. Since Heckles lives beneath Monica and Rachel, the stairs should be there, or at least the hallway should continue. When you see the hallway outside Monica and Rachel's apartment, the stairs are there. Therefore the layout of the building is inconsistent and incorrect. Also in "The One Where the Monkey Gets Away" when Ross knocks on Heckles's door, the stairs are where they should be.
Trivia: In "The One Where the Monkey Gets Away" Joey asks Mr. Heckles for the giant magnifying glass. At the end of this episode he ends up with it. Of course, as with many oddball items introduced in an episode, that is the last we see of it.
Continuity: Joey talks about how a girl he dated had the biggest Adam's apple. But in "The One Where They All Turn Thirty" Joey still thinks the Adam's apple is named after each individual person.
Continuity: Rachel says that Monica had sex with Fun Bobby out on the balcony. However in "The One Where Chandler Takes a Bath" Chandler wants to have sex on the balcony and Monica refuses.
Goof: Monica refers to the lawyer she used to babysit as Stevie "Fisher". In the end credits, however, his name is listed as Steven "Fishman".
Continuity: Monica orders Grilled Prawns, but in the episode, "The One Where Heckles Dies," she says she is allergic to shellfish.
Goof: At the concert Monica is recognized by a lawyer who remembers she was his babysitter when he was 8. Since graduation from law school normally occurs at about age 25, the babysitting would have been 17 years ago, when Monica herself was not much more than 8.
Trivia: In the end scene Joey overhears a call for Bob and leaps to answer the phone. He misses however and falls. The script called for Joey to answer the phone saying "Bob here", but Matt LeBlanc accidentally fell during filming and the producers went with that instead since they thought it was funnier.
Continuity: Ross's birthday is inconsistent. In "The One Where Emma Cries" Ross says his birthday is October 18th. In this episode (which aired October 19th), Ross is taken to the Hootie and the Blowfish concert on his birthday. However, in "The One with George Stephanopoulos", Joey and Chandler buy Rangers' tickets to celebrate Ross's birthday on October 20th, and Ross says that his birthday was seven months ago, implying his birthday is in March. Furthermore, in "The One with Joey's New Girlfriend" Ross tells Gunther his birthday is in December.
Continuity: In "The One with Frank Jr." Rachel tells Phoebe that she's not supposed to bring cups out of Central Perk. However, in this episode, not only does Phoebe drink from a cup outside of Central Perk, but Rachel brings it out for her. Also, in "The One with a Chick and a Duck" Gunther (who was actually the person to tell Rachel that the cups weren't supposed to be brought out of the coffee place) brings out a cup of cocoa for Rachel (possibly because of his feelings for her).
Goof: In the scene where Chandler is telling Monica that it will be a long time before she has to deal with her own baby, Monica folds her arms. When the camera angle changes, her arms are down by her sides. When the angle pans back to Chandler, her arms are folded again.
I'm in the shower and I'm writing a song
Stop me if you've heard it.
My skin is soapy, and my hair is wet,
and Tegrin spelled backward is Nirget.
Lather, rinse, repeat and lather, rinse, repeat
and lather, rinse, repeat... as needed.
"I Play For Me"
When I play, I play for me
I don't need your charity
La lalala lalalalalalala
lalala lalala lalalalalalala....
...was the double, double, double-jointed boy.
Stephanie knows all the chords...
Terry's a jerk!
And he won't let me work!
And I hate Central Perk!
You're all invited to bite me!
Smelly Cat, Smelly Cat,
What are they feeding you?
Smelly Cat, Smelly Cat,
It's not your fault.
Trivia: This is the first episode in which Phoebe's song "Smelly Cat" is played.
