American History Bonus test question??

Wut up ns, just thought i would drop this one on ya today cause its a pretty interesting question. Today in my intro to American history class we had a test... fronteirs, settlement, native americans slavery, yada yadaa same old bullshit about how high school just lies to you and they expect you to love history now cause we the ( "collegiate nobles") inspired a deeper interpretation into American History. Reading this bullshit book by James Lowen...pm me if you have read it and we can talk about about what a wack job this guy is and how much he hates his life and his job and the fact that hes more of a sellout than those he is accusing of being sellouts. ANYWAYS. I got to the last page of my test and the bonus question was: " what are the two WORDS that have been banned from high school history textbooks?" My first thought is like oh shit ik this but then i was like oh wait it says words not books....huh wtf? Ok so after reciting the english language aloud and 40000000000 hours later i still couldnt come up with anything good. I mean words? seriously. So eventually the will of my bad spirit gave in and NATURALLY i wrote..... NIGGER AND NIGGER. I stood up with just a smudgen of satisfaction and handed my test directly to my teacher with a small but noticeable grin. So now i come back to my dorm throw on some phish and ponder what ill do the rest of the day when i remember this question. So after a thorough hour long search on the internet i couldnt find anything...not a drop of banned WORDS. So ns this is why i come to you, for relief of my buirning desire to know the answer, for clarification, but mostly for tantamount in thought. So if you dont think its NIGGER NIGGER, what the bloody elll is it?
