A traveller who is a huge fan of seafood arrives in Boston for the first time. He leaves the airport and hails a cab. After he gets in, he excitedly says to the cabbie, "Hey, I'm new in town. Can you tell me a good place to go to get scrod?" The cabbie replies [in a thick Boston accent], "Pal, I've got to congratulate you. I've heard that question a lot over the years, but that's the first time I've ever heard it in the pluperfect subjunctive."
(I first heard that joke about forty years ago. Only it was the Librarian and school teacher)
