The Man Show on Comedy Central did the same gag with a bit about the woman's Sufferage movement(granting women the right to vote).
Jimmy Kimmel & Adam Carolla went around a large mall asking women to sign a fake petition
against women's Sufferage.
It always amazes me how fast people in public situations can be manipulated or are conditioned to react so fast.
Last month on New Years Day, I saw a group of empty lounge chairs in a large mall. I sat down & waited for a friend to shop in a Macys department store.
Within 10min, at least 5 other people sat down at the other chairs.
