Whenever I watch Sophie and Michael on their rocking horses, I'm reminded of something.
For a while I couldn't think of what it was. I had a vague vision of a kid...or a frog...rocking on a horse and tipping over. Then I remembered this scene from The Muppets Take Manhattan. (Click one minute into the scene to see just that moment.)
Of course that scene would get etched into my childhood brain and impress itself upon visions of my own peanuts rocking on their "hoo-wisses."
