Martin Short in The Associates (1979)

In this, the first starring vehicle for Martin Short, we meet a group of young lawyers just out of law school and starting their careers at the venerable law firm of Bass and Marshall. Among them is Tucker Kerwin (Short), an earnest young man always interested in doing the right thing. He's surrounded by a cast of characters that include do-gooders, sybarites, blue bloods and the beautiful and manipulative Sara James (Shelly Smith). Stealing many scenes is Emerson Marshall (Wilfrid Hyde-White) the senior partner who is going just a bit dotty. From all accounts, this series was just as charming as Taxi (1978), with which it shares creators. Look for Joe Regalbuto of Murphy Brown (1988) fame as a junior partner.

This series was cancelled after 9 episodes, though 13 were made. It's not available on DVD and only the opening credits are on YouTube. They're above, uploaded by carpalton.
