Never (And I do Mean Never) Absentmindedly Pet a Cat

Marko Ramius has thankfully never done this to me - he's a good kitty, but twice now - in the past year - I've reached down absentmindedly to pet a cat at my feet while working at my desk only to find the cat inverted. NOT THE CATS HEAD!!

I shiver to recall; once it was Big Puddy, and much worse, today it was Momo.
