The camera move on Tattletales below (around the :34 mark) is one of my favorites.
I like to think that Johnny is chuckling at whatever insulting thing the director just said over the headsets about Zsa Zsa while she was taking her sweet time to sit down, thereby delaying the next cue.
Just to me it seems like good directing is follow the action, hold a shot properly, catch reactions and change shots/angles when the situation needs it.
That's good (or just competent) directing. Exceptional directing is finding ways to make the natural action of the show more exciting.
Competent directing: Two-shot of Barker and the contestant as Barker tosses to the reveal of the big Golden Road prize, cut to tight shot of door #2 as it opens to reveal the prize.
Great directing: Over-the-shoulder shot as Barker is tossing to the reveal of the big Golden Road prize on the other side of the stage, continuous zoom in to door #2 as it opens to reveal the prize.
