Two friends, Smith and Jones, went together to play the slot machines at
Las Vegas. Each agreed that when his allotted money was gone, he would
go to the front of the casino and sit on the bench to wait for his friend.
Jones quickly lost all of his money and went to sit on the bench. He
waited and waited and waited and waited. After what seemed an eternity,
he saw Smith coming toward him carrying a huge sack of coins.
"Hey, Jones," said Smith, "How'd you do?"
"Well, Smith", said Jones, "you see me here on this bench - what do you
think? It looks like you hit it big, though."
"Oh yeah," said Smith, "did I find a good machine! It's way in the back.
I'll show it to you - you can't lose! Every time you put in a dollar four
quarters come out!”
