I was thinking about criticism launched against Jack for being too authoritative. Specifically, I was thinking of the times when guest stars arrived on the set late, hung over from the night before, and without knowing their lines. Numerous sources have reported that Jack read those guest stars the riot act -- on the set and within full earshot of other people.
Of course, the most tactful way of handling the situation would have been for Jack to take the guilty parties aside and speak to them privately about their behavior. But would we be able to do that? I might be able to do it the first time, but if it happened again, I'd be just as explosive as Jack was. I'd let loose with something like this:
"We did not bring you over here to have a good time. We brought you over here to work!" And, if the guest star threatened to walk out, I'd say, "Remember, you're under contract. How good is your lawyer at breaking contracts? Now, go sober up, clean up, and learn your lines. I expect to see you here bright and early tomorrow morning, ready to work." Then, of course, I'd storm into the office to rearrange the day's filming schedule to work around those absentee guest stars.
