[Spoilers] Great TV Show Endings

[bertowud]

Let's talk about our favorite endings to TV Series.

We've already discussed Seinfeld and The Shield elsewhere. What else do you have or is there something you'd like to add about the endings of these?

Consider this fair warning, there will most likely be lots of spoilers of other shows in this thread. I would still appreciate it if you use spoiler tags where appropriate. Not everyone has seen the ending of every show that will be discussed here.
