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.
