One thing that TV fans love to do is create their list for "My Favorite TV Shows of All-Time." Every few years I calculate mine, and for several years, the list didn't change that much.

Oh, maybe a couple of shows switched places or maybe a show dropped from number five to number eight, but for the most part the list stayed the same. That all changed a couple of years ago when I had to add both 'Mad Men' and '30 Rock' to the list. I still haven't figured out which two shows in the top ten I'll have to take off.

I'll also have to add a third show to that list, and that would be NBC's 'Chuck' (tonight at 8 on NBC). I don't know if it wedges its way into the top ten, but it's definitely top twenty. Here's why.
