I have fond memories of Sesame street. But that was A LONG TIME AGO. I haven't actually seen it recently although I have been annoyed by the second hand smoke of Elmo, who is to Grover what Scrappy Doo was to Scooby.
Apparently the parents who bubble wrap their kids each morning didn't like the Katey Perry outfit. I sort of like it. I suspect I would have liked it when I was 5 as well. But after the cries of the concerned they pulled the segment.
The real reason this should be pulled is not her ugly dress. It is THE MUSIC. Annoying and contrived with that gaspy breath vocal that is supposed to be from the heart or street or something.
That aside Kate does have nice gams.
