Please keep in mind before you vote that I am talking about the common house centipede, not any kind of millipede. I rather like many types of millipede: they have a sleek, Art Deco look, and when they feel threatened they wind themselves into a coil, which is neat-looking. Perhaps most importantly, they don't dart around in a maddening zigzag fashion.
What is your reaction upon seeing a centipede?
"Neat, a crawly thing!"
"Ew, a crawly thing."
Shrieking, flailing revulsion and/or terror
