http://www.youtube.com/watch?v=rmPRHJd3uHI (stupid song's been stuck in my head for 35 years)
http://www.youtube.com/watch?v=6mOEU87SBTU (ditto...and the hit song was based on the commercial BTW)
http://www.youtube.com/watch?v=nBYgbeT6ciI (and again...although I remember a pencil sketch animated version)
