What are your weaknesses?

I've harolded a laugh or two from a couple of interviews I was subjected to, when asked the age-old interview question- "what are your weaknesses?" and I answered, honestly, "chocolate". It really is the first thing that comes to mind- what are you supposed to answer to this question anyway? If we're talking peanut M&M's, there's no stopping me. I think it's fun to have a little fun with those boring, standardized and pre-approved "interview questions", I just hope that's not one of the reasons I'm able to publish a site with "jobless graduates" as the primary audience (laugh out loud). I don't think so.
