When I was in High School, our teacher assigned a book of mythology.  I think I was a Sophmore, and I’m pretty sure my teacher was one of those coaches who showed up for a year and did his time before moving on to a larger school in a larger town.  An argument could be made that these teachers left for public schools because we could be difficult.  Personally, I think we would have been far better behaved if books like Rick Riordan’s Percy Jackson and the Olympians existed instead of the yawn-fest we were assigned.  Whoever compiled that book of myths had to work really hard to make it so boring.
