The humor didn't come along until about the end of the original run. Others have said here that Mark Goodson was reluctant to use "funny" questions in the show's early days, when average questions were dry ones like "Name a flavor of ice cream" or "Name a popular New York tourist attraction." Very straightforward questions. Even back then, the "joke" questions were dropped in only occasionally. Seeing how 4 of the 6 players were civilians, the questions weren't designed to turn them into comedians. Later, with the focus on the witty all-celebrity panel, the 70s questions changed to play to their strengths.
