Dates: 1994-2004 (NBC) Episodes: 238 Why We Miss It: Where to begin? It was such a simple concept: having a bunch of friends live near one another in New York City. But each actor brought his or her character to life and gave a new meaning to the term "friend," allowing viewers to connect with and root for their favorites.

We pretty much cried our eyes out when we said goodbye after a decade of laughs.
