There were three girls on a boat. One was brown haired, the other was a red head and the other was blonde. Their boat was breaking down and it was 100 km to shore. The brown swam 15 km got tired, and drowned. The red head swam 50 km, got tired and drowned. The blonde swam 50 km, then got tired and swam the 50 km back to the boat. Vote and comment if you get it!!
