Here's a long one I heard the other day.
So there's this passenger plane, chock full of people flying, it gets some engine trouble so the captain adresses the passengers.
-"We're having some engine trouble and one of them has stalled, but do not worry we can make it on the other three."
But the trouble continues and another engine gives in.
-"Ok, we still have two engines so we can make it but we'll need to dump the luggage."
The passengers aren't too happy but hey, it's better to live without luggage than die with it. But there's even more engine trouble and the plane is down to it's last engine.
-"Right, so we're down to our last engine and if we want to survive some of us will have to jump. Now, we don't want to discriminate or anything so we're going alphabetically. First we need the African Americans to jump."
A young boy is travelling with his father and realises the captain is talking about them, so he turns to his dad.
-"Oh my god dad, that's us!"
-"Shut up son, they'll hear you."
-"We'll need more people to jump, so next up are Blacks."
-"Dad, it's us again!"
-"Shut up son, they might hear you."
-"Ok, that wasn't quite enough, we need the Coloreds to jump next."
-"Dad it's us again!"
-"Shut up son, today we're niggers!"
