Mrs. Epstein, feeling sorry for a pauper who appears at her door, invites him in, and gives him a substantial meal: chicken, kugel, wine, and two kinds of bread – black bread and challah.
The pauper devours everything he is given except the black bread. "The challah was wonderful," he says. "Do you have any more?"
"My dear man," says Mrs. Epstein, "we have plenty of black bread, but challah is very expensive."
"I know," says the pauper. "But believe me lady, it's worth it!"
