On an overseas flight, a lawyer and an older man were in adjoining seats. The lawyer asked the senior if he’d like to play a little game. The older man was tired and told the lawyer he just wanted to sleep.
But the lawyer insisted the game was lots of fun. “Here’s how it works,” he said, “I’ll ask you a question, if you can’t come up with the answer you have to give me a dollar. Then it’s your turn to ask me a question, but if I can’t answer it, I have to give you $20.”
The senior figured if he just got this over with, maybe he could get some sleep, so he agreed to play. The first question from the lawyer was, “How far apart are the earth and the moon?”
The senior stayed completely silent, reached for a dollar and gave it to the lawyer. Then he asked the lawyer a question. “What walks upstairs backward and comes downstairs forward?”
The lawyer was stumped. He thought and thought, trying to remember all the riddles he knew, searching every corner of his brain. He even cheated and asked the flight attendants and some other passengers.
Finally, he gave up and woke up the older man and handed him $20. The senior stuffed the twenty in his coat and immediately went back to sleep.
The lawyer couldn’t stand it. He woke up the older man and said, “I have to know, what walks upstairs backward and comes downstairs forward?”
The old man got out his wallet, gave the lawyer a dollar, and went back to sleep.
