As a humorous side-note...
The first day O'Reilly began his Christmas/Holiday rantings, Keith Oberman made an interesting discovery. As Bill spouted about the evils of the word "Holiday", on Fox News' website, you could buy, O'Reilly Factor "Holiday" ornaments.

Oberman put him on the day's "Worse, Worser, Worst" list (I believe he had the honor of holding all 3 spots that evening)...and the next day they had been changed to "Christmas" ornaments. I guess Bill watches Keith. lol
