### A little town in southern Illinois ...

A little town in southern Illinois had a sensational birth rate, and scientists decided to visit the place and find out the cause. So the sociologists, anthropologists, birth control specialists and other concerned scientists moved to the town prepared to do a six-month study of the causes of the town's high birth rate.

The day the research testing and all was to begin, the director of the million-dollar project stopped off at the single cafe in town and ordered coffee. When the waiter delivered his drink, the scientist detained him for a moment and asked, "Can you give me an idea was to why your town,above all others in this country, has such a high birth rate?"

The waiter thought a moment, then said, "I think I can. You see, every morning at 4:00, the C&A Railroad comes through town and blows its whistle at all three street crossings. That wakes up the folks here and, as youcan guess, it's too darn late to go back to sleep and too darn early to get up."
