There are three friends, a blonde, a brunette, and a redhead.
They were on a cruise ship and it was heading home.
When they got about 20 miles of shore the boat began to sink. The three girls jumped off and swam to a nearby island.
After being there a few days the brunette tries to swim to shore.
She gets about five miles off the island's shore and drowns.
After a few days pass the redhead decides that she will try. She gets about half way and drowns.
Now, realizing all her friends are gone the blonde decides to try too.
She swims for hours. She gets to where she can see the shore but she is so tired she decieds to turn around and go back.
