Once upon a time, the leaders of two neighboring towns gave $5 to 100 of their important essential residents to do whatever they wished.
The residents of Dumtown wanted to take their chances with some new lottery machines that had all kinds of game tickets that were colorful, with silly names and quick results. These games paid out 50% of the money played. All 100 residents quickly bought a $5 ticket and one lucky person won $250. Everybody was happy for this person, but some were a little sad because they didn't win. Some bought more tickets on their own.
Now, the residents of Funtown heard about a new game that just came into town and was offering plain tickets that paid 2 times the amount paid by the fancy machines or $500 for a $5 ticket. Everyone of the Funtown players, bought these tickets and one lucky person won $500. Knowing about the Dumtown experience, this person put $250 in the bank and threw a party for the other players with the other $250 of the lucky winnings.
Everyone in Funtown, had a great gathering that day and looked forward to playing another day.
