Glen, this one's for you - - an old one from my college days.

A salesman was given an assignment to attend a conference in Boston.
His associate, who was born there, suggested that he try the Scrod at a good restaurant.
"Scrod?", the salesman asked.
"It's actually Cod, prepared deliciously different.", replied the associate.
.
On the way from the airport to his hotel room, the salesman asked the cab driver, "Where can a fellow get scrod around here?"
The cabby said, "You know. I've heard that question a thousand times before, but never in the pluperfect subjunctive."
