It's true, there is a limit. You got to know the line. For me, it's concentration camps. You know the movie 'Life is Beautiful' can't be funny. The subject matter is not fertile, you can't grow anything in that. It's just ashes. So I have my limits. I use the N-word in 'Blazing Saddles'. But it was to show how despised, hated, and loathed this black sheriff was. Without the N-word, you couldn't have the story. You got to tell the truth.
