There was once a man with two sons. One was an optimist, the other was a depressionist. One day the man went to the doctor and said, "Doc, I don't know what to do, my sons are as different as night and day. I want them to just be normal." The doctor tells him, "Well do somethin really mean to the optimist, and really nice to the depressionist." So the man goes home. He spends all his money to buy the depressionist son everything he could possibly want. He shows it to the depressionist, and says, "I bought this all for you." His son just looks at him, the father asks if he likes it, to which his son replies, "Sure I do, but I really don't need any of it." The father was deeply upset for he had spent all of his money to try to make his son happy. Next the father sticks the optimist in a room filled with horse manure for the entire day. When he checks on his son later he finds him whistling and shoveling through the manure. The father asks him, "son, what are you doing?" And the son replies, "well dad, with all this horse p**p there must be a pony somewhere!
