A sad goodbye this evening to comic actor Pat Harrington Jr., who shuffled off this mortal coil today at the age of 86. Amongst Harrington’s most loved creations was the character of Dwayne Schneider on CBS’ “One Day At A Time”, a show that recalled a simpler time when a single mother of two had no qualms whatsoever about the building janitor visiting her and her teenage daughters at all hours of day.
