Plane Crash

Plane crashes on a desert island. 15 survivors. 3 Spaniards, two men and a woman, 3 French people, 2 men and a woman, 3 Germans (you get the picture), 3 Greeks and 3 Brits. Six months later.... The Spanish man had killed the other and was living with the woman. The French had a delightful menage a trois. The Germans had a strict rotation. Hans on odd days, Franz on even days. The Greek men were living together and had the woman doing the house work. And the Brits....were waiting to be introduced to each other.
