OK, I know I'm really obsessing about this, but the topography of that apartment building is driving me nuts.
In a recent episode (I don't think this is much of a spoiler) Chandler takes the fire escape. But he appears to go through a different window than the one they use to get onto the balcony. But in other episodes we see the fire escape is attached to the balcony; e.g. TOW George Stephanopoulos, when Rachel loses the pillow, and in TOW 2 Parts (?) when Rachel falls when taking down the Christmas lights.
...But *that* doesn't make sense either, since in some episodes (TOW Rachel Finds Out) we see that the window leads directly onto the balcony on that side. What is up with that building?!
