Intellectual Exercise at an Art Exhibit
A photographer put two pictures up side by side. The photographer announced to an audience attending his show that there was one difference between the two photographs. The difference was so easy to spot that even a five year old could tell the difference. For several hours, dozens of guests looked at the photographs and realized they could not spot the difference. Numerous guesses were made, but the photographer replied that none of the guesses were correct.
Finally, a five year old was brought in. The five year old immediately told everyone the difference between the two photographs. One was on the left, and the other was on the right.
