How does Sesame Street stay relevant after three decades of puppet-based children's programming? The same way everyone else does: celebrity drama!

Sesame Street pushed the envelope with two mildly-scandalous vids this week -- a parody of HBO's vampire-porn drama, True Blood, and a boobie-licious guest appearance by Katy Perry -- and now the show is riding a wave of attention after parents inevitably disapproved.

Check out all the drama and see the videos after the jump.
Katy Perry Banned from Sesame Street
Katy Perry's appearance on the show was actually pretty innocent. She played a game of tag with Elmo and sung a toned-down kiddie version of her hit single "Hot and Cold." The uproar was about Katy's famous breasts, which were covered in a modest-for-her sheer mesh thingamabob.

After parents complained, Sesame Street pulled the clip from YouTube and decided not to air it. That inspired Katy's fiancée, comedian Russell Brand, to have a little fun on Twitter at Sesame Street's expense.

"Today's Sesame Street will not be brought to you by the number 34 or the letter D," Brand said on Twitter, presumably referring to Ms. Perry's cup size. He followed that up with a cheeky, "Can you tell me how to get, how to get to Sex-with-me Street?"
True Mud
Sesame Street pushed the envelope a bit more with a parody of HBO's True Blood, a show with its fair share of nudity, death and gore. The kids' version is called "True Mud," and instead of being a secret vampire, the main character is a secret Grouch, looking for some mud for his mud bath.

It's a fun rhyming lesson, but is Sesame Street just looking for attention by capitalizing on a current hit show that's very much for grown-ups only? I don't know. Sesame Street has parodied plenty of movies that kids wouldn't be allowed to see. The only difference is that those movies probably weren't on the cover of Rolling Stone at the time.

"True Mud" hasn't aired yet, so it remains to be seen whether they'll pull it, too. I hope not, because "That's not True Mud, it's a potato!" is a hilarious line at any age.
