There is a blonde, brunette and a redhead on an island and theare starving to death, so they all descide that the best chance tehy have of surving is to try and swim to the next island with food, and water, so the brunette goes first gets half way, gets tired and drowns, then the redhead goes next she also gets half way gets tired and drowns then the bolnde goes she gets half gets tired and swims back (might have to think about this one to get it, if you dont get blonde jokes)
