Video of the Day: Broadcast News is Really Stressful

Apparently these newscasters need a vacation. Just as soon as Bill O'Reilly looses his $hit, Sue Simmons drops the F bomb live during a news bumper. Here's a little background: Bill goes ape shit crazy because of a malfunctioning teleprompter while he's trying to film his closing. I'm not exactly sure what happened with Sue. She's talking about raising groceries prices they cut to footage of a cruise ship and then out of nowhere you can hear her yell out "Da fu@k are you doing?!
Ma'am!
I actually saw it live and sat stunned for a few seconds. It was like the time when Jane Fonda Dropped the C-Bomb on the Today Show. Why am I always alone when this stuff happens!
In any event she apologizes for the 'blunder' but what we all really want to know is "Da fu@k happened" to cause her to to curse someone out. And who was she talking to?
