There are two kinds of people. There are Letterman people and there are Leno people. I think Jay Leno is a nice guy but I don't think he's funny. Funny is a very personal thing and he just doesn't do it for me. Nice, yes. Funny, no. I prefer smartass Letterman.
Therefore, I had never heard of the Fruitcake Lady. You have to click on the link (that's an order) and watch some of these videos. She is my new idol.
