Presidents and presidential assassins are like Las Vegas and Salt Lake City. Even though one city is all about sin and the other is all about salvation, they are identical, one-dimensional company towns built up by the sheer will of true believers.

Being a nerd, which is to say going to far and caring too much about a subject, is the best way to make friends I know. For me, the spark that turns an acquaintance into a friend has usually been kindled by some shared enthusiasm like detective novels or Ulysses S. Grant.

I'm always disappointed when I see the word 'Puritan' tossed around as shorthand for a bunch of generic, boring, stupid, judgmental killjoys. Because to me, they are very specific, fascinating, sometimes brilliant, judgmental killjoys who rarely agreed on anything except that Catholics are going to Hell.

But when I am around strangers, I turn into a conversational Mount St. Helens. I'm dormant, dormant, quiet, quiet, old-guy loners build log cabins on the slopes of my silence and then, boom, it's 1980. Once I erupt, they'll be wiping my verbal ashes off their windshields as far away as North Dakota.

That's what we Americans do when we find a place that's really special. We go there and act exactly like ourselves. And we are a bunch of fun-loving dopes.

Buffy's high school was built on top of a vortex of evil, the Hellmouth. And whose wasn't?

If I looked in the mirror someday and saw no dark circles under my eyes, I would probably look better. I just wouldn't look like me.
