Speak for yourself, eh.
They annoy me because they set up such stupid pointless conditions. Why would anyone want to go to market with a fox and chickens? Who carries so much gold that it will sink a boat, who would want to hire and trust a riverman with such a marginal boat, and what happens if the next passenger weighs five pounds more?
It's more fun to ask questions back and make them admit the questions are pointless.
And I don't want to work at companies that think such questions have anything to do with how I work, so I figure I may as well have fun blowing up the interview.
