Here's a further twist to this story:
After the N-word row, another finger-wagging assault on poor old Mark Twain – for smoking
"In this Twain-targeting censorship, it was not the word “nigger” that was airbrushed from history, but a cigar ... Because Holbrook spends virtually the entire 90 minutes of the play chomping on a cigar, just as Twain did for most of his life, and these days smoking in public is considered even more morally depraved than uttering the N-word."
