Jenn:
As someone who has both hosted shows and been a tech (still am), I know that anything disturbing enough to distract the host is by definition worth "pmsing" about.
Hosts are hired for many reasons, but one of the chief reasons is their ability to work quickly, reliably and with a minimum of fuss - there is always more production to do than there is time. A prima donna would quickly find themselves pushed out of the studio, almost regardless of talent.
Notice the number of people walking by the camera, according to Berman: "Seven."
Seven people had an urgent need to walk past the camera? In sixteen years of television production the only person I've seen walk past the camera was the stage manager. And that was slowly, carefully, quietly and as unbotrusively as possible.
