A passenger plane starts losing altitude.....

A passenger plane starts losing altitude so the pilot decides to dump the cargo afterwards their still losing altitude so he goes on the intercom and says
"we're still losing altitude and need to throw off some passengers to save the rest so to be fair we will do this in alphabetical order"
he then proceeds to say
"ok are their any African Americans"
no one raises their hand
"ok are their any Black People"
no one raises their hand
"ok are their any Colored People"
still no one raises their hand

When a little boy looks up at his mom and says
"momma aren't we African Americans, Black People, and Colored People"
she says
"oh no son today we're Niggers"
The little boy looks at the Mexican on the other side of him and smiles and says
"Ha you gotta go first"
the Mexican then says
"oh no senor cause today we're Wetbacks"
