I haven't seen anybody else post this, so here is an article my buddy just showed me on the top 25 weirdest interview questions of 2010.
I think some of these questions are just stupid, specifically the martial arts question, #3. But a lot of them get very creative. Again, they are looking to see how you think through the question, not so much that you get it correct. My friend said he will memorize the amount of ridges on a quarter along with the answers to all the questions, and then he'll be golden. I told him, no, they will think you have issues and ding you- besides the fact that they will ask a different random question that you won't know the answer to.
Anyway, have fun with it.
