5. Today Show viewers - After Good Morning America announced that Katie Couric will sit in as co-host this week, the show's NBC rival countered with the bizarre move to bring on someone famous for being publicly humiliated by Katie Couric. Sarah Palin will co-host tomorrow's Today (a phrase only half as ridiculous as that decision) and conduct an interview with Ryan Seacrest, who apparently has a "big announcement." We hope it's that there's a carbon monoxide leak in the building.
