The manager of a large corporation got a heart attack, and the doctor told him to go for several weeks to a farm to relax. The guy went to a farm, and after a couple of days he was very bored, so he asked the farmer to give him some job to do.
The farmer told him to clean the shit of the cows. The farmer thought that to somebody coming from the city, working the whole life sitting in an office, it will take over a week to finish the job, but for his surprise the manager finished the job in less than one day.
The next day the farmer gave to the manager a more difficult job: to cut the heads of 500 chickens. The farmer was sure that the manager will not be able to do the job, but at the end of the day the job was done.
The next morning, as most of the jobs in the farm were done, the farmer asked the manager to divide a bag of potatoes in two boxes: one box with small potatoes, and one box with big potatoes. At the end of the day the farmer saw that the manager was sitting in front of the potatoes bag, but the two boxes were empty.
The farmer asked the manager: "How is that you made such difficult jobs during the first days, and now you cannot do this simple job?"
The manager answered: "Listen, all my life I'm cutting heads and dealing with shit, but now you ask me to make decisions.
Physics Teacher: "Isaac Newton was sitting under a tree when an apple fell on his head and he discovered gravity. Isn't that wonderful?"
Student: "Yes sir, if he had been sitting in class looking at books like us, he wouldn't have discovered anything."
