On a farm out in the country lived a man and a woman and their two sons.
Early one morning, the woman awoke, and while looking out of the window onto to the pasture, she saw that the family's only cow was lying dead in the field. The situation looked hopeless to her -- how could she possibly continue to feed her family now?
In a depressed state of mind, she hanged herself.
When the man awoke to find his wife dead, as well as the cow, he too began to see the hopelessness of the situation, and he shot himself in he head.
Now the oldest son woke up to discover his parents and the cow dead, and he decided to go down to the river and drown himself. When he got to the river, he discovered a mermaid sitting on the bank. She said, "I've seen all and know the reason for your despair. But if you will have sex with me five times in a row, I will restore your parents and the cow to you."
The son agreed to try, but after four times he was simply unable to satisfy her again.
So the mermaid drowned him in the river.
The youngest son, woke up and saw his parents dead, the dead cow in the field, and his brother gone.
He decided that life was a hopeless prospect, and he went down to the river to throw himself in. And there he also met the Mermaid.
"I have seen all that has happened, and I can make everything right if you will have sex with me five times in a row."
The young son replied, "Is that all? Why not ten times in a row?"
The mermaid was somewhat taken aback by this request.
Then he said, "Hell, why not TWENTY times in a row?"
Finally, she said, "Enough!! Okay, if you will have sex with me
twenty times in a row, then I will bring everybody back to perfect health."
Then the young fellow asked, "Wait! How do I know that twenty times in a row won't kill you like it did the cow?"
