Dates: 1996-2001 (NBC) Episodes: 139 Why We Miss It: This Emmy Award-winning show captivated audiences from the get-go, as 23 million viewers tuned in to watch its premiere. And the premise itself is hilarious: A group of extraterrestrials pose as a human family in order to observe human beings on earth, which they deem as the "least important planet." Their view of earth is often distorted, considering they gather much of their information via the media—especially television—rather than firsthand experiences. Oh, and the names of the three male "family" members? Tom, Dick and Harry.
