What's My Line?
In 1980, Mark Goodson-Bill Todman Productions, creators of "What's My Line?", produced "That's My Line" which also highlighted the unusual occupations of ordinary people. However, the show was developed as a reality show and had no panel or game elements. "What's My Line?" announcer Johnny Olson was the announcer, and Bob Barker was the host for the show which ran for two seasons on CBS.
Chicken eyeglasses
On January 16, 1955, Sam Nadler of the National Farm Equipment Company of Brooklyn appeared on CBS' popular primetime television show, "What's My Line?" The show was in the format of a guessing game, in which a panel attempted to determine the line (occupation) of contestants. Show officials listed Mr. Nadler's occupation for the audience as "sells 'eyeglasses' for chickens". After the panel was unsuccessful in guessing his occupation, Mr. Nadler's identity was revealed and he stated that his company sold 2–3 million pairs of chicken eyeglasses per year. "What's My Line?"s director, Frank Heller, said in 1958 that the show's "most unusual occupation" over its then eight-season run was "...the gentleman who makes eye glasses for chickens."
