From an NPR interview with a writer who worked on a game show in which contestants tried to guess how Americans answered various questions:
SMITH: So when you say you're a writer for a game show, what does that mean?
WILK: Great question. Nobody knows. I have no idea.
ROMER: David gets to work cooking up questions to give the polling company. The polling company does its job.
WILK: And it was the only question that we ever wrote where we ever got a response from them saying, is this actually what you want us to be polling? And we said, yes. And the question was - we were going to ask people, have you ever been decapitated?
SMITH: (Laughter). But...
WILK: They were sure we had made a mistake, and we had not.
SMITH: As far as David remembers, by the way, 4 percent of Americans answered that they had been decapitated.
ROMER: Seems high.
