This 635th and final episode of a great American classic deserves much more than the trashing the other reviewers have given it. They are absolutely right that it lacks fancy plot and character development and fights to the death. This last episode presumes that the viewer doesn't need any further lessons in morality that the previous 634 episodes bludgeoned them with. It's a fresh and light-hearted tribute to the chaotic, petty entanglements that our world was built upon. In the end, everything works out for the best and the chaos continues presumably forever. This final tongue-in-cheek peek through the keyhole into the convoluted nature of our existence is very refreshing. For those of us who can see the forest in spite of the trees, it tells a truly meaningful story... with all of life's drama and problems and entangled obligations, it is still worth living.
...And the lesson in life never ends... Don't judge this quaintly tangled tale too harshly, it was meant as an uplifting send-off and not something to be critically acclaimed or bashed.
Happy trails to all who made this series the icon that it was.
