20. "L.A. Law" (NBC) — 22.1 million viewers

After eight seasons, "L.A. Law" made its final closing argument on May 19, 1994. On the series finale, Becker (Corbin Bernsen) is feeling his best days are behind him at the ripe old age of 42. At the same time, the firm plans to celebrate senior partner Mckenzie's (Richard Dysart) 65th birthday, but he has a surprise for them: He's retiring. That throws the firm into chaos and forces the partners to look for new jobs.
