1. The Trip to Vegas
Just before the show was about to be aired, director James Burrows took the cast to a trip to Las Vegas. Burrows asked them to enjoy as much as they can, because he knew that after the show is on-air, the cast will never be able to roam around freely. They will be always hunted by their fans and paparazzi for pictures and autographs.
2. The Huddle before Episodes
The six actors will have a huddle before every episode. This made guest stars like Tom Selleck and Paul Rudd feel a bit left out.
3. Watching episodes together
The girls would watch every episode together at Jennifer Aniston's home.
4. The girls chat box.
Recently Jennifer Aniston revealed that the three girls still have a chat group and they take regular updates of everyone.
5. Negotiating for a common salary.
The entire cast was paid an equal salary of 22,000$ in the first season. However, it has been allegedly reported that in the consequent season, the cast had a different salary. Some were paid higher than the other. In 1997, the cast negotiated that they will be having an equal salary.
It was something unique in the history of television. That was also a reason that the cast received 1million dollars each for each episode of the last season.
