Isn't it enough that we have tornadoes?

I'm sitting at my desk and start to feel a little wobbly.  Literally felt like the ground was shaking.  First thought: too much coffee?  I ask a co-worker if I'm crazy or if the floor is moving.  She felt it too, but she's pregnant, so that could mean anything.  Co-worker #2 confirms; his wife sent him an email seconds after the tremor and asked if he felt it, a mile away from her.  Phone buzzes - tweets from friends in Norman about feeling their first earthquake and pictures falling off the wall.

Woah.  My tummy still feels wobbly thinking about it.  I've never been so accutely aware of the fact that I work on the 16th floor of a 50 story building.  Yikes!
