I find this unit interesting its discussion of cursing in Shakespeare, most notably since he doesn't go for the obvious Taming of the Shrew or Romeo and Juliet, but rather King Lear! First he presents some Lear style "cursing" (whoreson, knave, etc...) and then gets into his students' own "street" rewriting. It's personally not to my taste, I don't think you have to sprinkle liberally with swears to get your point across, but who knows, maybe that's exactly how his kids talk in their regular life? There's discussion at the end, too. For instance in one Cordelia rewrite she drops an f-bomb while talking to her dad, and people question whether that's realistic for her character.
Warning, if it wasn't obvious - dirty words abound.
