When he appeared in September 1962 on "What's My Line?" he had to sign
in as "Mr X", due to the fame of his name. He was credited, to the

identity was revealed to the panel, he explained that, while working on
the film "The Hustler", he had to train Paul Newman, but Jackie Gleason
seemed to already know his way around the table.
