For many years the best work of TV comedy pioneer Ernie Kovacs was hard to find, but since last year it’s become hard to ignore. In April 2011 the Shout! Factory label released a handsome six-disc set, The Ernie Kovacs Collection, that spanned the comedian’s career on national TV, from 1951 to 1962, when he was killed in an auto accident. This year the label has released Ernie Kovacs: The ABC Specials, an indispensable single DVD of the brilliantly surreal half-hour shows he created in the last year of his life, and the CD Percy Dovetonsils . . . Thpeaks, a long-lost comedy album starring his most reliably funny character, the lisping, martini-sipping, chronically delighted poet laureate.
