From a recent Carson documentary, it appears that Johnny Carson and Angie Dickinson had a thing for each other but it never worked out in OTL that both were on the market simultaneously.
OK, given that otherwise-microscopic, seemingly random events can exponentiate, let's suppose that for some obscure reason, both were single at the same time for however brief a window--and that they decided to make it official and marry. How might that affect late night TV, prime time TV, and other show business venues--if at all noticeably?
