Every round of this show says that the answers came from a survey of 100 people. Wikipedia says that there have been at least 8000 episodes. Say there’s five rounds in each game (a pretty conservative estimate): that makes 40,000 of these surveys.
And at 100 people per survey, that makes 400,000 people. Or one out of every 750 people in America.
I’ve never been called by their show with questions. I don’t know anybody who has been. Do you? Sounds fishy to me.
