A family had twin boys whose only resemblance to each other was their looks. If one felt it was too hot, the other thought it was too cold. If one said the TV was too loud, the other claimed the volume needed to be turned up. One was terribly pessimistic, and the other equally optimistic. One Christmas their father hit upon a way to cure them of their differences. He went out and bought the fanciest, most exciting train set for the pessimistic boy. For the optimist he got a Christmas stocking and filled it with horse manure. Christmas morning came, and after the boys had opened their gifts, the dad asked each what Santa Claus had brought him. "Well," said the pessimist, "I got a train set, but I'll probably cut myself putting the track together, and it's got an electric transformer, so I'll probably electrocute myself, and, besides, the whole thing will probably break in a week." The dad was pretty disappointed that he had failed to cheer up the pessimist, but figured he may still have cured the optimistic boy. "What about you, son," he asked the optimist. "What did you get?" "I got a pony!" he exclaimed, jumping up and down with excitement. "Only I haven't found it yet!"
