Black means Nigger
Speaking about nigger,here's a joke about them from a subforum

A professor is sent to darkest Africa to live with a primitive
tribe. He spends years with them, teaching them reading, writing,
math and science.
One day the wife of the tribe's chief gives birth to a white child.
The tribe is shocked, and the chief pulls the professor aside and
says, "Look here! You're the only white man we've ever seen and
this woman gives birth to a white child. It doesn't take a genius
to figure out what happened!"
The professor replied, "No, Chief. You're mistaken. What you have
here is a natural occurrence, what we in the civilized world call
an albino! Look at that field over there. All of the sheep are
white except for one black one. Nature does this on
occasion."
The chief was silent for a moment, then said, "Tell you what. You
don't say anything more about that sheep and I won't say anything
more about that white child."
