Okay, you alll probably already knew it's based on Sam Hill but did you know there was a person named Sam Hill? He was a bit of an eccentric and was into all kinds of weird projects. He built a castle for his wife, Mary and also recreated a full size replica of Stone Henge. You can still see it today at Maryhill State Park near Maryhill, Washington, near the Columbia river.
Here's the state parks website:

Thought it might be interesting. Ever wonder what the term Doozy was based on?
