A young boy was trying to grow cauliflowers. He had heard about a technique which his gardener grandfather said would never work. The system meant that the growth of the plants could not be observed.
On the day of the local gardening competition his grandfather watched as the boy revealed each plant. After the third stunted one his grandfather shook his head and went home. The next one was a giant. The boy took it to the competition tent - which was deserted - and managed to fit it into the display by removing its leaves.
After the judging - the boy and his grandfather looked at the results. The grandfather admired the cauliflower which was now sporting a "2nd" rosette. A judge remarked that if it had had its leaves it would have been the winner.
The grandfather put his spectacles on and picked up the plant's identification card saying admiringly "Now let's see who this expert is".
