An American, a French and an Arab are in a hot-air balloon

They spend a nice trip when suddenly the french realizes " Hey men, we don't have enough propane to safely reach the ground ! We must lose weight ! "
Frantic, they dropped food, clothes and everything that they don't care about, they still don't have enough propane and they really start to panic
Several minutes later the Arab says "Ok, I will drop the oil, I've too much in my country". The American thinks a bit then says :Ok, I'll drop the gold, I've too much in my country".
At this point they both look at the French, who, in the blink of an eye, takes the Arab and throw it out of the hot-air-ballon, the American stares a him, shocked and says "what have you done ?!", the French calmly replies : "I've too much in my country".
