Who Cares Why Manhole Covers Are Round?

My latest Patch article follows on my last one about my (so far) half-assed job search. Have you heard of these jackass interview questions that are like the riddle of the Sphinx? Have you ever been asked any weirdo questions in an interview? Do I really have to be prepared to answer questions like these?

The whole thing makes me so tired I think I'm going to take a nice long break from barely looking for a job...
