Is Nothing sacred anymore?!?!?! Sesame street now has an adult rating?!?!?!?

Why? Because when Mr. Hooper died IRL, they let him die on the show to teach kids about mourning? Or iis it their old "3 of these things belong together, three of these things are kind of the same" song? I've heard some crazy blatherscythe about that show not always being PC, but to give it an adult rating!?!?!?
