For all kinds of different reasons, this has been kind of a bad week for me in terms of blog posting (obviously). The in-laws are visiting right now, and so far a good time is being had by one and all, and I might be able to get back in the swing of things next week, unless the stack of essays I need to grade falls over and smothers me. Deep sigh.
Anyway, in lieu of actually having something intelligent to say (and I have a whole thing working in my head about how both the Democrats and Republicans are lyng about the whole WMD thing in Iraq, though the Republicans are clearly the bigger and more dangerous and more expensive liars), I offer this link to a study about the ineffectiveness of tin foil skull helmets.
