I'm sure this is a topic that has been discussed before, but I couldn't find the thread. Hopefully, another thread won't be too annoying for anyone.
I am interested in buying the "Friends: The Complete Series Collection" DVD set. The picture previews shows the back of the box and it says it comes with 19 hours of extras. What extras are included on the DVD? And a point of interest, just so it doesn't look too general of a question, is the Leno special that aired right after the final episode included in the extras?
