Which is a plausible argument anyway. But Dwayne McDuffie – comic and TV writer -proves it. Elsewhere the horrible spectre of continuity has been discussed with regards to comics – where the occasional anal fan community pick nits which should be left alone. So Dwayne considers the occasional world of US TV crossovers – and finds out that one show in particular is a veritable Kevin Bacon of TV shows.
Said show is St Elsewhere. And if you remember how St Elsewhere ended, then suddenly the whole of US TV is destroyed. Wow. (A good supporting role from the omnipresent Detective Munch of course.) Look and learn.
