They were definitely more difficult than usual and this provides a big incentive for people to just google questions that they can't think of an answer for because the scoring system kills you for an incorrect answer.
Personally I quite like the tough questions cos it gives everyone a chance to learn some interesting stuff but really the game should be about how good you are at identifying what others would answer rather than finding a correct answer yourself. When there are only a few possible answers, people have a big incentive to google rather than give the only answer that they can think of which seems a lock to be the sheep answer.
