Not going to wax to crazy about conspiracy, but seriously...a little strange. Teaching about washing hands, and covering mouth when sneezing/coughing is one thing. My personal opinion is this cross the line. Would be just as strange to have an episode that discussed the dangerous of vaccinations. Neither is something I expect to see on a children's show, on public television. I understand that show exists to help little ones work through their concerns and fears, but this isn't really a matter for children. Is it? No harm done I guess....just weird!
