one time there were 3 ladys stranded on an island, on said, "oh! i will swim over to land, it only 20 miles!" so she swam, and got tired after 5 miles, and drowned after 10 miles. the next one said, "i will check if she is ok" so she swims. she gets tired after 10 miles. and drowns at 15 miles. the last lady, a blond, says to herself, "i will go see if they are ok!" so she doesnt get tired until 19 miles, so she says, "Well, im too tired. i cant do this anymore." so she swims back.
