I really hate this animal. The first time I saw it was in an otherwise spotless public restroom at the U of U. It sped into my stall as I sat helpless, my legs immobilized by the jeans crumpled around my ankles. Thinking quickly, I tapped one foot which scared it into changing its course. It headed toward a drain in the floor and disappeared.
That was at least three years ago. Then just last January I turned on the sink to wash some dishes and another one (or the same one?) raced out of my garbage disposal toward the plate I was holding. I turned on the faucet, then the garbage disposal.
A quick google search of things like "legs drain insect fast" and "scary sink bug" revealed that I was being terrorized by a scutigera coleoptrata, also known by its overly-endearing common name, the house centipede. One message board described it as a the Satan spawn of a spider and a centipede.
