NOTE 1: The poem starts off with one of my favourite jokes ever. No one to whom I have told it has ever thought that it was funny.
NOTE 2: Scrod is a fish which is associated with New England.
This guy is visiting Boston for the first time.
He gets into a taxi and says to the driver,
“Do you know where I can get scrod?”
The driver says, “I’ve heard that question a million times,
but never in the pluperfect subjunctive.”
Taxi drivers are the Buddha.
Bartenders are the Buddha.
The meaning is, "Hey, buddy,
why are you tying yourself in knots
over something so
as conjugation, anyway?
Do I have to draw you a diagram?"
The man in the back seat realises
that pluperfect is too much to ask
and achieves nirvana.
He leaves without giving a tip.
