I worked in a small office where they were constantly asked to go out to work on weekends. Since I was a new employee, the boss asked me:

Do you want to work on Saturday?

I can’t on Saturday, I have a Sabbath.

Q. Are you a Jew? (The chief was a Jew and was already glad that he found a landlord.)

Saturday is Jewish.

Maybe then on Sunday?

I go to church on Sunday (I replied)
