There are three women stranded on an island.
One is brunette, one’s a redhead, and the other one is a blonde.
There is land in sight. “I have an idea!” the redhead says.
“We can swim there!”
So the redhead jumps into the water, swims 1/4 of the way, and drowns.
The brunette says, “I’m a better swimmer. I can get there.”
She manages to swim 1/3 of the way and she drowns.
The blonde dives into the water, swims 1/2 of the way, and looks around.
“I’m pretty tired.” she says. “I’m gonna swim back.”
