Um...do we evacuate?

I love it when I think I have something medically wrong with me, and it turns out to be something mechanical.

Last week, it was when my monitor went bad and I thought I was having a migraine aura, until someone else confirmed that the pixels were jiggling.

Just now, I thought the Vioxx I took for me knee earlier was making me dizzy (which it does sometimes) until I heard someone else say "Is the floor shaking?" It was shaking hard enough that some of our monitors were moving and my chair was physically moving.

Earthquake? Hmmmm....
