Drudge reports that Katie Couric literally slapped around an editor when he slipped the word "sputum" into her text.
Long ago I worked at NBC News. Usually I was behind the scenes -- way behind the scenes -- but I remember a rare instance when I had to go to the studio where they shoot the Nightly News. Tom Brokaw was there in a corner, reading his text out loud to himself before the broadcast, rehearsing different emphases and intonations. I would suggest that if Ms. Couric takes her job seriously, which after all is nothing more than reading a script, she should at least read the thing beforehand.
