A blonde, a brunette, and a redhead are stuck on a stranded on a deserted island. The brunette says," The nearest land is about 20 miles away." So she starts to swim there. 5 miles…she got tired. 10 miles…too tired to go on. So she drowned.
Well, the redhead says," Maybe she is there now." So she swims 5 miles, 10 miles, 15 miles…too tired. So she drowns.
Then the blonde thinks to herself ' Maybe they're there now.' So she swims 5 miles, 10 miles, 15 miles.
Finally, she gets to 19 and 7/8 of a mile. She can almost stand where she is. She yells out," I CAN"T GO ON!!!"
SO SHE SWAM BACK!!!
