A family had twin boys whose only resemblance to each other was their looks. If one felt hot, the other thought it was too cold. If one said the TV was too loud, the other insisted the volume should be cranked up. They were complete opposites, one an eternal optimist, the other a doom and gloom pessimist.

Just to see what would happen, on Christmas, their father loaded the pessimist's room with every conceivable toy and game. In the optimist's room he filled it with horse manure.

That night the father passed by the pessimist's room and found him sitting amid his new gifts crying bitterly.

"Why are you crying son?" the father asked.

"Because my friends will be jealous, I'll have to read all these instructions before I can do anything with this stuff, I'll constantly need batteries, and my toys will eventually get broken" answered the pessimist twin.

Passing the optimist twin's room, the father found him dancing for joy in the pile of manure.

"What are you so happy about?" he asked.

To which his optimist twin replied:

"Somewhere in here, there's gotta be a pony!"
