Once, there was a group of construction workers building a road. Under a nearby tree, their manager sat watching in the shade, sipping lemonade. The construction workers worked away, while wondering why they were working, and their manager was sitting and sipping lemonade. So finally, one of the workers threw down his shovel in frusteration. "Why is it, that he gets to sit and sip lemonade, and all o' us have to keep working?" He asked his fellow workers. The workers decided to draw straws to see who should confront the manager, and ask him why he was sitting and sipping lemonade, and they were working. Lo' and behold, the one who drew the straw was the first one to talk. So they sent him up to the manager. The man walked up, and asked the manager, "why is it that you are sitting here sipping lemonade, while we're working away?
"Now now," the manager replied, "we do everything for a reason here. Let me show you." The manager walked up to a metal post, and put his hand on it. He pointed at it saying,, "Punch my hand as hard as you can." The construction worker tried to punch the manager's hand as hard as he could, but the manager moved his hand out of the way just in time. The worker slammed his fist into the metal post.
"Storm it!" The construction worker cursed. "What did you do that for?"
"That," The manager replied, "Is why I'm sitting here sipping lemonade, and you are working under the hot sun."
So the construction worker headed by to his friends, with the answer. He looked around for something hard like the metal post, but the only thing he could find that matched the hardness, was his head. "This is what he said." The construction worker placed his hand on forehead. "Punch my hand as hard as you can."
