All "bloopers" actually went out over the air, right?
I guess not every blooper was aired; on some very rare occasions, if a blooper was really bad, they had no choice but to bite the financial bullet and reshoot a scene. On one of the MPI videos - I don't remember which one - they showed a reshoot of a scene where Julia was having a conversation with Tony Peterson in his office, although I couldn't see what the blooper was. Maybe it was something on the technical end, like a camera jamming or something. I also heard, but wonder if it's just a DS urban legend, that once in a blue moon, when the performers really, really wanted a blown scene reshot, even though they were told that if things screwed up they just had to keep going, that they would stop, look into the camera and say an expletive. Then there was no choice but to reshoot. Like I said, as to whether or not this was true, I don't know. But it makes for a good story.
