A Joke on the Bartender

A minister, a priest, and a rabbi walk into a bar.

The bartender asks, "What is this, a joke?"

This joke has become one of Marash Girl's favorites, a joke which she found while reading the introduction to Jim Holt's STOP ME IF YOU'VE HEARD THIS:  A HISTORY AND PHILOSOPHY OF JOKES. NY, W. W. Norton, 2008.
