Here's a tasty little joke from Eugene Volokh:

Fish: I had some tasty fish for dinner tonight, here in Boston, and this reminded me of the old joke: A man is on his first visit to Boston, and he wants to try some of that delicious New England seafood that he'd long heard about. So he gets into a cab, and asks the driver, "Can you take me to where I can get scrod?" The driver replies, "I've heard that question a thousand times, but never in the pluperfect subjunctive."
