I'm slowly accepting that B&T will never be that daring/outrageously offensive/parodic again. The fear of legal action just seems to dominate the show's writing too much.
As long as they parody a franchise they can be as outrageous as they want to be. Part of their problem though is that they were caught with their pants down using Pirates characters with characteristic monologues and no actual attempts to parody them. Mistakes were made, lessons were learned; stay within legal guidelines and the road is golden. The past few years have been bad out of sheer laziness and/or incompetence.
