Over the decades I've enjoyed a little Johnny Carson, David Letterman, John Stewart, Stephen Colbert, and Arsenio Hall, but late-night talk shows aren't my thing. Conan's my favorite, but I've never watched him much either. I prefer his writing to his late-night act -- his few episodes of "The Simpsons" are all classics, and "Not Necessarily the News" is one of the first "adult" shows that I liked when I was a kid.
I've seen very, very little of Jay Leno, John Oliver, Trevor Noah, Jimmy Kimmel, or any of the others. I'm glad for those who enjoy 'em, but they're really, really not for me, especially guys like Oliver and Noah, who basically just preach political rhetoric to their audiences.
Anyone remember The Chevy Chase show? If you don't, consider it a blessing. XD
