8. 'Hello, Larry'
And goodbye, Larry. Under the weakest of pretenses — he was an old Army buddy of Diff'rent Strokes' paterfamilias Philip Drummond! — NBC designed MacLean Stevenson's new comedy as a spin-off of one of their few hit shows at the time, partially in the hopes that fans (Stroke-heads?) would follow. It was apparent from the very beginning, however, that the story of a divorced man fleeing to the Pacific Northwest to become a radio talk show host was not the thing to lift them out of their slump. (The same basic premise would be used for Frasier years later, with vastly different results.) Hello, Larry quickly went from great white hope to the butt of jokes and is still considered one of the worst sitcoms of all time.
