Ken Jennings

You watch an old 'Jeopardy!' and the categories alone are very plain. 'Poetry,' or 'Movies,' or 'Physics.' If you watch it now, though, there'll be a theme board where the categories are all Hitchcock movies. Lots more jokes, lots more high-concept categories and questions.

Whether or not you agree with Ayn Rand - and I have certain issues with some of her beliefs - the woman can tell a story. I mean, the novel as an art form is just in full florid bloom in 'Atlas Shrugged.' It's an unbelievable story. The characters are so compelling, and what she's saying is mind-expanding.
