I looked at both intros here (the second one does't load) and the first one isn't it. When aired on PBS there would be a sound effect for a certain part (e.g. a "zzzzit" for the light bulb, wind when Bill clears the screen, etc.) but there would be only one effect for one part (e.g. just the bulb). When aired in syndication they would have all of them. I'm requesting this version.
