Thirteen women are kneeling around a circle. A whistle blows, and suddenly all thirteen women began shouting out the names of their sons and daughters, while frantically waving their arms. At last, a whistle blows once again, and one of the women is awarded a trophy. What kind of insanity is happening here?
The thirteen women, along with their thirteen sons and daughters (all babies of a crawling age), are competing in a "Fastest Crawling Baby Contest." Initially, all of the babies were placed in the center of a circle, with the women kneeling outside of that circle. When the whistle blew, the first baby to crawl to their mother outside of the circle was the winner, and the trophy was subsequently awarded to her.
