Potsy, Potsy Webber

I am teaching my students about medical emergencies and the cardiovascular system. Every year I teach this class I think about the Happy Days episode when Posty Webber taught a class about the flow of blood through the body with a great song. It's now used on the St. Joseph aspirin commercials as well. I've always wanted to find it and use it, and now I have it!!! Check it out http://www.dgs.k12.il.us/heart.htm
