The sermons

In a large Florida City, the rabbi developed quite a reputation for
his sermons, so much so that everyone in the community came every
Shabbat.

Unfortunately, one weekend a member had to visit Long Island for his
nephew's bar mitzvah. But he didn't want to miss the rabbi's sermon.
So he decided to hire a Shabbas goy to sit in the congregation and
tape the sermon so he could listen to it when he returned.

Other congregants saw what was going on, and they also decided to hire
Shabbas goys to tape the sermon so they could play golf instead of
going to shul. Within a few weeks' time there were 500 gentiles
sitting in shul taping the rabbi.

The rabbi got wise to this. The following Shabbas he, too, hired a
Shabbas goy who brought a tape recorder to play his prerecorded sermon
to the 500 gentiles in the congregation who dutifully recorded his
words on their machines.

Witnesses said this marked the first incidence in history of
artificial insermonation.
