I have asked a few questions that put people on the spot but not something silly or off-the-wall like those questions in the comments and article. The most interesting responses have come from the questions similar to this:

On Wednesday your transportation tracking project is updated representing 6 months of development and 3 months of testing and quality assurance. Everything runs well on Thursday and Friday, and you and your team leave for the weekend. Monday morning you are met at the door by a security offices and you are brought directly into the Boardroom. You are informed that at 6:23 am on Sunday there appeared to be a "glitch" in the new system and two trains met head on in central Missouri. As the potentially responsible person what are the first three things you ask or do?

We learned a lot about the potential employees.
