I taught English in Korea. One year, they hired a black teacher.

But only after they held a meeting of the Korean faculty to vote on whether they'd allow it, and then a vote of the parents to see if they'd allow it. I have no idea how close the votes were or weren't, but they hired a black teacher.

First day she's there, I'm in my high-level 6th grade class and this kid asks "hey teacher, what's a nigger?"

Yeah, uh, really glad he waited til she wasn't in the room for that one.
