Chaim Yankel phones El Al. "Yes, can I help you?" asks the booking clerk.
"I'm looking to book a flight to Tel Aviv for this coming Sunday," says Chaim Yankel, "and I’m wondering if there are any seats still available."
"Before I can answer that," says the El Al clerk, "I need to know how many people are going to fly with you."
"Oy vey, what a silly question to ask," replies Chaim Yankel. "How should I know – it's your aircraft, not mine?"
