Have them but your trade list doesn't have anything on it that I need.

Hi bencasey,

Thanks to a generous member with whom I made a trade, I am now in need of only one other episode. Do you have it -- #13: "The Out Of Town Trip"?

Let me know, because if the sitcoms in my trade list (including the recent additions) don't strike your fancy, I may have some other stuff that could interest you!

The lead character was Tucker, played by a young Martin Short—so young that he was still pronouncing “about” as “aboot,” proving all the Canadian stereotypes to be shamefully true. In the first episode, Tucker is drafted out of Harvard Law School to be an associate at a major law firm. On the first day, he meets the other new associates, the gorgeous blonde blueblood Sara (Shelley Smith) and Leslie (Alley Mills) a Hollywood homely working class woman with a ton of student loans to pay off. (This sets up a classic Betty and Veronica situation throughout the show: Short pursues the unattainable Sara while mostly ignoring Leslie’s crush on him.) And he meets Mr. Marshall (Wilfrid Hyde-Whyte), the elderly, dotty, rambling, but unexpectedly sharp senior partner, who is sort of like Latka and Reverend Jim combined and turned into an old British man—whenever a scene is slow, bring on Whyte to deliver a funny line or a rambling monologue. The role of Louie DePalma-esque creep is filled by the unctuous Elliot Streeter (Joe Regalbuto), who believes unconditionally in all the evil lawyer stuff that the other characters have moral qualms about. And as the token blue-collar guy, there’s Johnny Danko (Tim Thomerson), the disco-suited gofer and office stud.

I have just tracked down that elusive final episode. My collection is now complete. Anyone interested, please PM me!
