When a man applied for a job at the railway station, he was asked, “Suppose you saw a train coming from the east at 100 miles an hour. Then, you noticed a train coming from the west at 100 mph. The trains are both on the same track and just a quarter of a mile apart. What would you do?” The man replied, “I’d run and get my brother”. “Why would you ever do that at such a critical time?” he was asked. The man replied, “Because my brother’s never seen a train wreck”.
