Trivia: In the scene where Ross has just explained to Joey & Chandler that he has to give up Marcel, there is an advert break. Immediately after the break, the shot shows the three guys sitting on the sofa in the coffee house. If you look at the positions that their hands are in, they are mimicking either "See no evil", "Hear no evil" or "Speak no evil". I think this was done deliberately but since there isn't much laughter, I don't think the studio audience spotted it.
Trivia: In the "One where Nana dies twice" at the end of the episode the cast looks over pictures of Ross and Monica's Nana. One of the pictures is labeled 'Me and the gang at Java Joe's'. Java Joe's was one of the name possibilities for Central Perk during the show's creation stage.
Trivia: In many of the first episodes, there is a beam going from the ceiling to the floor in between the kitchen and the living room. You can see it when they show the door. In "The One With The Giant Poking Device" Ross actually runs into it. In the majority of the later episodes, the beam is non-existent. The beam became the trademark for director James Burrows. Whenever he returned to direct an episode, the crew intentionally added the beam.moviemaster101
Trivia: When the girls are out on the balcony discussing what the boys would be like in bed, their discussion foreshadows their future romantic entanglements. Phoebe speaks highly of Joey, Monica of Chandler, and Rachel of Ross. Although Phoebe and Joey were never technically together, they often acted as a pair.moviemaster101
Trivia: The scene where Rachel is on the balcony is the only scene in Friends in which Monica, Joey, Phoebe and Ross ALL appear together without Rachel and Chandler. Chandler was at the ATM vestibule, and Rachel was on the balcony. This scene begins with Phoebe singing "New York City has no power..."
Trivia: Phoebe singing giant pigeon was a deleted scene from the pilot. When it was used years later in DVDs with extended footage the audio was not very good and they had to get Lisa Kudrow to redo the audio. (This information can be heard on extended DVD audio commentary for the pilot).Dan23
