Well-written!  Interesting.  There is a video on youtube to go with it.  I always thought that he was the most important member of the cast.  Schwimmer was first and was the rock, Perry was the most versatile, problem-filled, and endearing.

I’d like to read more about why roles are scarce.  I don’t see why that would last.
