There should be a notice ahead of the movie that says 'This movie is PG. Can you read? You are a Parent. Do you understand what Guidance is? Or are you just another stupid toddler who thinks they're an adult simply because they've grown older and, unfortunately, have developed fully-functioning sexual organs? Would you like some committee somewhere to decide *everything* for you? Get a damn grip, will you? And shut the wretched kid up!'
