The story behind the Muppet
Scene around the Web 2.0-sphere: Surprising stories behind 20 Muppet characters.
[The Count] used to be more sinister — he was able to hypnotize and stun people and he laughed in typical scary-villain-type fashion after completing a count of something and thunder and lightning would occur.  He was quickly made more appealing to little kids, though.
But I liked the Count who laughed and caused immediate weather phenomena, even as a little kid. I think they talked to the wrong little kids before changing him.
