Sesame Street Likes True Blood

What shows does Sesame Street think kids watch nowadays?! Between this, the Mad Men parody, and the Katy Perry appearance, Sesame Street is becoming more and more adult friendly. I'm enjoying the skits, but I wonder how much kids get these jokes. I hope kids aren't out there watching True Blood - that show is far too graphic! And I doubt kids have the patience for the slow burn that is Mad Men.
