Katy Perry busts out on 'SNL', mocks 'Sesame Street' boobie ban

Buxom pop star Katy Perry made fun of the banned "Sesame Street" video on "Saturday Night Live" by appearing in a sketch all about her breasts. The "Street" video (where she's wearing a bright satin dress and running after Elmo) she shot for the childrens show was deemed not suitable for preschoolers by outraged parents. Seriously.

On "SNL," Katy played a 16-year old library volunteer who has been told to wear looser and less-revealing clothing when she does storytime. She discusses the situation on the mock daytime chat show, "Bronx Beat," hosted by Amy Poehler and Maya Rudolph.
