I've never actually met a real live humorist. Well, not in person at any rate. However, one summer, having a lot of time on my hands, I discovered unexpected treasures lurking in the local public library. Among the nuggets I unearthed in those musty stacks was a book by humorist Robert Benchley. To this day I remember one of his quips. He wrote, "There are two kinds of people in this world; those who divide the world into two kinds of people and those who don't." After laughing out loud, I became pensive. I wondered why the quip was so funny. A year or so later, I formed a theory. Humor is based on the unexpected.(br)In the passage above, the topic sentence and the thesis are one and the same.
