We are Zulus

The Zulus!

An airplane is flying over the United States at night. The pilot says: "Ladies and Gentlemen, the plane is losing altitude and all the baggage must be thrown out."
A little later, the pilot says "We're still losing altitude, we must throw anything out that is in the cabin".
The plane continues its descent despite more things being thrown out. Pilot: "Still going down - we must throw out some people". There's a big gasp from the passengers!
Pilot: "But to make this fair, passenger will be thrown out in alphabetical order. So... A... any Africans on board?"
No one moves.
"B... any Blacks on board?"
No one moves.
"C... any Caribbeans on board?" Still, no one moves.
A little black boy - asks his dad: "Dad,...what are we?
The father very concerned about the son and his life replies, " Tonight son, we are Zulus!"
