Think Fast was an American quiz show that ran on ABC from March 26, 1949 to October 8, 1950. The program revolved around a group of five panelists who would compete to see who had the most to say about a particular subject. They sat at a large table, each getting a chance to sit at the "King's" throne by out talking the others on subjects decided by the host. The regular panelists were Leon Janney, David Broekman, who was also the show's musical director, and Eloise McElhone. The moderator was Mason Gross for the first episodes, then Gypsy Rose Lee afterward. The series originally aired on Saturdays until April, followed by Fridays until September, then Sundays for the rest of its run.
