It's funny, my sports addiction pretty much keeps me from watching "normal" TV. I'm a year-round sports nut, so there is basically some event to watch every night.

I sort of watch Grey's Anatomy by osmosis with my wife, and she has also gotten me into ER-- although I don't like it nearly as much as I used to.
And here's a dirty little secret: My wife usually DVR's Gilmore Girls each week-- and I kinda like it. OK, I really like it
