Sometimes it's not what you say, but how you say it that matters. I could listen to Billy Bob Thornton's character in the movie Sling Blade talk for hours and be entertained. He reminded me of the way my uncles sounded when I was growing up. They didn't say much, but when they did it rolled off their tongues in a simple country fashion that was soothing to me as a boy. And when they spoke they cut right to the chase.
"Some folks call it a sling blade, I call it a kaiser blade...hmmm."
Karl, Sling Blade
Frank: I like the way you talk.
Karl: Well I like the way you talk.
There is something to be said in using economy when it comes to words. I think it is okay to have an impressive vocabulary. I just don't think it is always necessary to use it. It's part of the difference between Journalism majors and English majors.
Instead of saying "I really like potatoes sliced into verticle slices about a half inch wide, deep fried in vegetable oil and served with salt," just say what Karl in Sling Blade said: "I like them French fried potaters."
In that way, I consider myself a simple man. Sometimes you just have to say what you have to say and shut up. There are lots of radio talk show hosts and pompeous bloggers who could benefit from that approach.
