Plane Crash

A passenger jet looses all of its engines and the passengers know they are going to crash. There are three women sitting next to each other in one of the rows.
The Italian woman opens her purse and begins pinning money all over her clothing. The other women ask why and she says that when the rescuers begin searching the crash site they will see the money and rescue her first.
The Jewish woman begins putting on all of her jewelry, saying that the rescuers will see the gems and rescue her first.
The black woman begins taking off all of her clothing. The two other women ask why she is undressing. She says, "Everybody knows the first thing they always look for is the black box."
