(no room for who are in thread title) Heavily recurring as in most of a season. The shows can include flops, but has to be at least 20 seasons of assorted shows (or one show if it has giant longevity like The Simpsons). Can include sitcoms, dramas, and dramedies, but no movies, game shows, talk shows, or reality crap. Busted pilots that were never ordered to series do not count. Actors only in this thread, no adding producers, writers, directors, etc.
