Finally found The Metric Marvels

For several years I have mentioned to people, including students in my classes, about cartoons that I saw as a little kid that were like School House Rock only they introduced me to the metric system.  There was a Meterman (in the cartoon I learned that a millimeter was about the thickness of a dime and that a meter was a little longer than a yard) and there was a Wondergram (in the cartoon I learned that a gram was about the weight of a paper clip).  Try as I might, I could not find out about these cartoons.  I was beginning to think I had imagined the whole thing.  Well, tonight I finally stumbled across information about them - they were called The Metric Marvels and more details can be found here:  http://www.thefullwiki.org/The_Metric_Marvels.  A black and white introductory clip can be seen here: http://www.youtube.com/watch?v=eW98QCk2FdA.
