His audition for his most famous role, television's "Cousin Itt" of Addams Family (1964), was as mysterious to him at the time as the popular character would soon be to millions of viewers. Arriving at the studio, he received little more than a quick looking over by the director and producer, who merely said "That's Itt!" and told him to come back Monday morning and report for work. He returned home for the weekend, pleased to have passed the audition but still completely unaware of who (or what) he had been hired to portray on Addams Family (1964). Not until Monday morning, just hours before he made his debut as "Cousin Itt", did he have any idea as to the nature of the character.
