Rick, the show ran from 9/21/63 to 12/21/63-- which would have amounted to fourteen shows; but, the same week that the show was cancelled by ABC, JFK was killed in Dallas. Thus, all scheduled network programming that weekend, including Saturday night's scheduled episode of "The Jerry Lewis Show" on ABC, was preempted. So, the total broadcasts over those three months and two hours was, indeed, an unlucky thirteen!
