Rizzo really came off as Wembley to me in that video, cute but would have been funnier if he said rat on a hot tin roof, I know it wouldn't have made much sense with what he was doing and this is now the second scat joke the Muppets made.
Sadly and I don't think they are aware but the word Scat has a much more disgusting meaning behind it these days as I recently found out on a website.
