"Hello Larry" was part of Fred Silverman's attempt to ruin, er, resurrect NBC from the ratings doldrums. Amongst other great works he begat "Supertrain," "Turnabout," "Diffrent Strokes," and "Hello Larry." Despite it's abysmal badness, the show ran for two seasons simply because so many of the network's offerings bombed that they had nothing better to run, a fact that beleagured network execs cheerfully admitted to. While the show was lousy and never drew good ratings (despite often being paired with "Diffrent Strokes") Mac at least was a "name" actor and supposedly a proven commodity. Poor McLean Stevenson, so loveable as the boob Henry on "M*A*S*H" never again found material as good. Unfortunately unlike fiascoes like "In the Beginning," "Condo," or even "The McLean Stevenson Show," "Hello Larry" ran long enough for people to remember it as the series that wouldn't die, and poor Mac is now probably as well remembered for being trapped in TV purgatory there than he will be for "M*A*S*H."
