Wiggles World!

From: http://www.smh.com.au/news/people/now-the-wiggles-are-movie-stars-in-their-own-theme-park/2005/08/06/1123125942993.html
"Staff at Dreamworld have already had a "Wiggles boot camp" to ensure they deliver Wiggles-style behaviour when working with children inside the theme park attraction....
"Paul Field said Wiggles World staff would be instructed not to say things such as "hello boys and girls" (the Wiggles never separate children by gender) and to smile until their cheeks hurt."
and then once more, later in the article, for good measure...
"The Wiggles don't separate children by gender, never saying "Hello boys and girls". They only say "Hello everybody" or "Hello everyone".
