Excerpt:Â Have you ever noticed how we associate the light bulb with a good idea? I mean, what happens in a comic strip when a character gets a good idea?
You see a little light bulb over his head.
There's a reason for that.
The light bulb really is a good idea.
And, by light bulb, I mean the incandescent light bulb invented by that great American, Thomas A. Edison. I do not mean the new, ugly, fluorescent knockoffs made in China.
