Don't believe any of the bad things you've ever heard about Mr. Rogers, he was a very sweet man.  Even the picture you will occasionally see on the internet of him giving the middle finger, is actually a picture of him counting taken out of context.  Anyways, you WILL watch the attached video more than once.  I'm up to five times.  Click through.

This video is one of the sweetest and strangest things you will ever see. It's also very catchy.  Keep in mind that this thing was actually put together by PBS (home of Mr. Rogers).  Watch this, then bookmark the page.  If you ever have a friend that's pothead over, play them this video, it will freak them out and probably scare them straight.
