One of this week's $0.99 movie rentals on iTunes is The Natural. This is the movie that introduced me to the word "bastard" as a child. I had no idea what it meant or even that it could be considered a bad word. I just picked up from the movie that it's something you call someone when you're mad at them.
Of course, this got me into trouble when I called my brother Travis a bastard at a family gathering. Nobody really heard it, but Travis promptly tattled on me and I got my mouth washed out with soap. The worst part was that I had absolutely no idea what I had done wrong.
I'll freely admit that there were plenty of times in my childhood when I truly deserved to have my mouth washed out with soap (though my personal preference was for Lux, I found Palmolive had a nice, piquant after-dinner flavor -- heavy with a touch of mellow smoothness), but this wasn't one of them.
