"The West Wing" (8 p.m., NBC): A four-time Emmy winner for Outstanding Drama, "The West Wing"

"The West Wing" (8 p.m., NBC): A four-time Emmy winner for Outstanding Drama, "The West Wing" traveled a rare prime-time path -- starting off at breathtaking heights, then stumbling a bit after creator Aaron Sorkin departed, and finally reinvigorating itself for a thoroughly mesmerizing stretch run. The final episode, which will be preceded by a re-airing of the pilot, has incoming president Matt Santos and his staff nervously gearing up for inauguration day. Meanwhile, President Bartlet, C.J and the others fondly look back at their sometimes-turbulent, but steadfastly idealistic White House years.

The bloopers-and-highlights reel is a real hoot, too.
