Chandler tells a story of a director firing a crew member on the first day of each shoot, later stating that it may have been Orson Welles. It was in fact Welles, who would fire an employee at random in a public and humiliating way to scare the other employees.
When Ross wakes up he is asked what song Phoebe was singing and he answers: "The one with the cat", which is the title of an episode earlier in the season.
The girl Ross dates in this episode lives in Poughkeepsie. Lisa Kudrow (Phoebe) is an alumna of Vassar College in Poughkeepsie.
Towards the end of the episode, Ross is seen traveling to Poughkeepsie to break up with one of the girls, but has fallen asleep. He apparently stays asleep until arriving in Montreal, which is approximately a 9 and a half hour journey by train (via Amtrak's Adirondack service). Therefore, it's highly doubtful he would've remained asleep for such a long period of time. Additionally, the woman on the train in Montreal states "it's just a two hour ferry ride to Nova Scotia." No passenger ferry services exist between Montreal and Nova Scotia (they are in fact connected by road), and even if they did the trip would take significantly longer than two hours (would take 80-90 minutes by plane, and 10-14 hours by car, several days via waterways).
Phoebe complains that Rachel doesn't rhyme with anything good, and Monica adds that Rachel's dad used to call Rachel "pumpkin." "Pumpkin" is one of the few words in the English language that has no rhymes.
