A cowboy was riding his horse across his pasture.  A snake
spooked his horse and bucked the cowboy off.  The cowboy 
cursed at the snake and yelled, "Don't bite me!"  

The snake said, "No, I'm a genie snake, I can give you three
wishes.  What would you like me to grant you?"

The cowboy thought for a minute, then said, "A million dollars 
in the bank." 

The snake said, "Granted, next."

Again the cowboy thought, then said, "The most beautiful 
wife in the world."

The snake said, "Granted, next."

Then with a great big smile on his face he said, "I want to be 
hung like my horse."

The snake said, "Granted," and slithered off.

The cowboy got on his horse and rode home as fast as the 
horse would take him.

He ran into the house and into his bedroom.  There stretched 
across his bed in a sexy negligee was the most beautiful 
woman in the world.  

So he picked up the phone called the bank and asked for his 
balance.  The bank told him he had one million and forty nine 
dollars.  He rushed into the bathroom.

Unzipped his pants and let out the most blood curdling cry.   "I 
forgot I was riding OLD NELLIE!"
