tv game shows - end all be all

There is a show that ask people to try to figure out how a percentage of people would have responded to a question.

Made me think it might be something to try here.

Of course, I haven't surveyed anyone so there is no REAL way of knowing the answer. But it still might be interesting to see how people on the board would answer the question. Perhaps other people can think of similar questions?

My question to you is this:

If everyone on earth was given a button that would destroy the earth if it were pressed, what percent of the people do you think would push the button?
