Barmecide Feast

Barmecide Feast. In the Arabian Nights it is related that a member of the Barmecide family invited a starving beggar to a feast, and set empty dishes before him, giving each some magnificent name. The beggar entered into the joke so well that his entertainer caused the imaginary banquet to be followed by a real one.
