The best goof I heard about it was last night on Twitter when someone said, “This episode is brought to you by the letters T and A.”

Elmo must have had a heck of a time trying to maintain eye contact.

Katy Perry’s appearance on the long-running PBS children’s show has been pulled after parents complained about the singer’s cleavage-baring dress…

[A] Sesame Street spokesperson issued a statement to UsMagazine.com early Thursday morning, deciding to side with the angry viewers:

“Sesame Street has a long history of working with celebrities across all genres, including athletes, actors, musicians and artists. Sesame Street has always been written on two levels, for the child and adult. We use parodies and celebrity segments to interest adults in the show because we know that a child learns best when co-viewing with a parent or care-giver. We also value our viewer’s opinions and particularly those of parents. In light of the feedback we’ve received on the Katy Perry music video which was released on You Tube only, we have decided we will not air the segment on the television broadcast of Sesame Street, which is aimed at preschoolers. Katy Perry fans will still be able to view the video on You Tube.”

Thus does a cutesy TV segment aimed at preschoolers magically transform into a viral video cult classic popular with beta males. Which, I assume, is what Perry was shooting for by choosing that dress. She didn’t really want this to air on “Sesame Street.” Did she?

Two clips here, actually, one of the forbidden duet and the other of the newest “Sesame Street” production — a spoof of the hypersexual HBO vampire drama “True Blood.” This guy has your exit question.
