Had it:

The above was the Sesame Street record I had, and I listened to it constantly. To this day, once I start thinking about the song "Rubber Ducky You're The One", I have a hell of a time trying to get it out of my head. It just keeps playing in my head over and over and over and over.

As an afterthought, looks like Bob there swiped one of Mr. Rogers cardigans from his closet..
