A gentile woman came to work as cook-housemaid in a Jewish home. When she came home for leave, her relatives asked her what kind of people the Jews were.
"The Jews are rather nice. They are always most polite to me, give me presents, pay for medical help for me. Really, no complaints whatsoever. Only they have strange holidays. They have a holiday named Shabbat, when they eat in the dining room and smoke in the toilet. Then they have a holiday called Tisha B'Av which is a reminder of their great Temple which was destroyed in Biblical times. They smoke in the dining room but eat in the toilet, and they have a holiday named Yom Kippur, when they both eat and smoke in the toilet."
