Just to get started, one that is fresh on my mind (hand, arms, stomach, credit card, and medical insurance)...
1.) Picking up a snarling cat, even your own.
Awww, I am sorry to read this, I hope there aren't too many scars?
Another one close to mind - slowing down when you see that you are passing someone with an unleashed pit-bull mix...my idea was that slowing down would be less intimidating for the dog.
