Entertainment lawyer Jeremy Geltzer has written a fascinating book about the history of film censorship in the United States. It's called "Dirty Words and Filthy Pictures: Film and the First Amendment."

This episode has generated a lot of (positive) online commentary. We don't actually use any dirty words in it, but the topic is mature, so it may not be appropriate for younger or more sensitive listeners.

But the rest of you will enjoy the, um, heck out of it.
