Really, after they get over their bellyaching about how underpaid they are for nine months of work at "only" $60,000 per year ("people just don't realize how hard it is to teach") and look at what they actually know...well, a rock comes to mind.

The evidence suggests the NEA may even be recruiting "teachers" from various mental asylums. Apparently "credentials" from an institution is considered a "plus."
