What Time is it?

A young Jew and an old Jew are riding on a bus in Jerusalem. The young Jew asks, "Excuse me, sir, what time is it?"

The old Jew doesn't answer.

"Excuse me, sir," the young Jew asks again, "what time is it?"

The old Jew looks up him, but still doesn't answer.

The young Jew is puzzled, "Sir, forgive me for interrupting you like this, but I really want to know what time it is. Why won't you answer me?"

The old Jew turns toward the young man and says, "Son, the next stop is the last on this route. I don't know you, so you must be a stranger to this land. If I answer you now, according to Jewish tradition, I must invite you to my home. You're handsome and I have a beautiful daughter. You would fall in love with her and you'd want to get married. And tell me, why would I want a son-in-law who can't even afford a lousy watch?"
