On Joey's Magna Doodle: Two palm trees on a tiny island.
Time Index 32:09. As Gina is talking she crosses her legs. The camera angle changes in a split second and she is sitting without her legs crossed.
Joey says that Sir Anthony Hopkins is his favorite actor, then amends that to The Rock. However, it was established in Friends that Joey's favorite actor is Al Pacino; who was the entire reason he got into acting.
When Gina and Joey are talking, you can see the tattoo on Drea de Matteo's ankle.
When Michael is talking to his girlfriend on the phone, it's practically the same conversation Ross had on Friends with Julie somewhere in early season 2, with the slight difference of Michael's girlfriend actually hanging up. Coincidence?
Joey mentions to his sister Gina that the only time he said "I Love You" was to a girlfriend he had in New York (Rachel, from Friends), but she was pregnant, having his best friend's child.
This was the second time he spoke about his past in Friends.
Joey tells Carmen that he still uses her 1998 Baywatch calendar and that he has missed Christmas for the last four years in a row. In Joey and the Plot Twist they celebrated Christmas and Joey was absolutely aware and excited.
Nitpick: Joey says at the beginning of the episode that he has dated women from all over the world except for Iceland, and is pleased to discover in the end that Sara is part Icelandic. But when he takes a map right after this discovery with red pins for each country from which he's ever dated a woman, we can see that Iceland already has a red pin.
Goof: Near the middle of the episode, while Joey, Alex and Gina are in Joey's apartment discussing Alex's issue, we see Alex sitting with a yellow shirt with a folded sleeve, when the camera position changes the sleeve is not folded, then on the third view when Alex is standing up the sleeve is again folded.
Joey says that he will do something he has never done before. While he is dating Sara he will not see any other women. However, Rachel said on Friends that Joey had really changed, and the whole week they were going out he didn't date anyone else.
Joey's date with Sara in this episode is VERY comparable to his date with Rachel in the season 8 episode of Friends, "TOW Joey Dates Rachel". The exact same "moves" are used.
Nitpick: Mary Teresa teases Gina about the fact that their father was holding the back of 'his' neck forcing him to propose. Joey says that 'Dad's face was pretty red', indicating that he saw it and knew who the father was. However, it is later revealed that Jimmy (Adam Goldberg) is Michael's father and Joey had no idea at all.
It is revealed that Alex speaks Spanish.
It would be a little bit weird that Kimberly Evans died in her show because of naturel causes, since she said she's only 51 years old...
It was never mentioned what happened to Joey's character Dr. Drake Ramoray between the end of Friends and the start of Joey. It is now revealed that he was killed off for the second time, the first being in the Friends episode The One Where Dr. Ramoray Dies.
At the beginning of the episode, the show producers send Joey a clip that they're showing at the ceremony, but at the ceremony, they read the nominations without using any clips.
Joey says that he likes to call his Valentine's Day ritual the Valentine's Day Massacre.
The Valentine's Day Massacre is the name given to to the events surrounding the death of seven people in Chicago in 1929. The conflict took place between two rival mob gains. The seven people were lined up against a wall and executed, hence being given the name massacre.
During Gina's tap dance, you can see the tattoo on Drea de Matteo's ankle.
Joey makes a toast to the Knicks. It was well established in Friends continuity that the Knicks are Joey's favorite team.
