In 1945, Ace signed on as one of the writers of "The Danny Kaye Show". Previously he and Jane had been part of a series of celebrity guests who filled in for Kaye while he entertained the armed forces troops who were overseas. When Kaye moved his show from New York to Hollywood, Ace resigned. Whether writing for himself and Jane or for another performer, Ace's rating system of how well a script would do was based on the number of cigars he smoked while writing it. One cigar meant the show would do very well, while four cigars meant this program or episode was most likely hopeless. Ace was sued in 1940 because of the name he selected for a character. He used the first name of one of his staff coupled with the last name of another. Unknown to Ace, this resulted in the name of a real person who was publicly embarrassed by the use of his name on the show. He then began the practice of having those on the program use their own names for their characters.
