Apparently a Katy Perry segment on Sesame Street was nixed because of the amount of cleavage visible.
“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 viewers’ opinions and particularly those of parents. In light of the feedback we’ve received on the Katy Perry music video, which was released on YouTube only, we have decided we will not air the segment on the television broadcast of Sesame Street, which is aimed at preschoolers.”
Maybe this is an obvious suggestion, but why don't they just change her dress?
