Everyone for some reason likes to act like they know more about gambling odds then someone else to prove that 

they are one step ahead of the other guy. Here is a great story just for those fellas.

A father with 17 race horses dies. In his will he left his 3 sons all 17 horses.

1/2 must go to my oldest son.

1/3 must go to my second son.

1/9 must go to my youngest son.

Now you try it: How many horses does each son get?

So as the 3 brothers are fighting over who gets what, because there is no way to divide up 17 racehorses. Well, a
 
sports book director from Las Vegas, rides by on his horse and gets off and tells the boys that he can help them 

divide up the 17 racehorses. He then added his horse to the group, and made 18 horses.

He gave the oldest son, 9 horses for is ½.

He gave the second son, 6 horses for his 1/3.

He gave the youngest son, 2 horses for his 1/9.

And the sports book director grabbed the horse that was left over for him self and rode off into the sunset.

Of course you know, that the horse that he grabbed was stronger and smarter then the one he left behind.
