I’m going to recite a very old joke that my father used to tell.

A fine Jewish doctor had done very well in his practice for many years, and to reward himself, he went an bought a new Jaguar sports car. Maybe he felt a little Jewish guilt for spending so much money, so he went to the Rabbi of his orthodox synagogue, and said, Rabbi, I’d like you to make a blessing on my new Jaguar. The Rabbi said, “I know what a blessing is, but what’s a Jaguar?”
