Winters was best known for ad-libbing while in the guise of one of his many wacky characters, like Maude Frickert, the sweet old lady with oft an innuendo-laced comment, and Princess Leilani-nani -- the world's oldest hula dancer. Winters released nearly 20 comedy albums and his most notable film roles include the classic "It's A Mad, Mad, Mad, Mad World," and "Eight On The Lam."
