I started to name this post "Elvis," but up popped "Elvis, Barbie and Rebellion." When I went to search my other blogs to see why that was happening, I found "Elvis, Battle of New Orleans, Pinky and the Brain, Cavemen."
Those two sets of words, separated from their origins, are more interesting than what I had originally intended to write about Elvis. I invite you ponder for a moment what I might have been thinking.
If you get tired of that, you are welcome to explore the first one and the other one, at your leisure.
