Seriously? OMG! WTF?

As we end one year and begin a new one, Me TV takes a look back the beginning and endings of some of the shows of their lineup like Cheers, The Mary Tyler Moore Show, Happy Days, Star Trek and several more.
Seeing them side by side like that, show how much they changed from their first day to their last one.
I enjoyed it so much, I want to see them do that with more shows. What shows would you like to see the first and last scenes of simultaneously like that.
