Naming kids after books/TV shows/Movies? ?

I work in a daycare, and some new clients came in today....a 4 year old girl named Lorelai, and 2 year old tripets (a boy and 2 girls), Jess, Lane, and Paris. My first thought was gilmore girls because I love that show, and their mom confirmed that she loves gilmore girls as well. What are your thoughts on naming kids like this? I think it's kinda odd. I think naming 1 kid after one show or whatever is okay....one of my favorite names for boys is Sawyer, which I got from the show lost...but I would never name my kids Sawyer, Jack, Kate, and Hurley haha. I was curious to see what others think.
