When I was a kid I was hiding/running from some friends. While walking on a fence through two very close buildings I saw a "cat" in my way up ahead. I didn't want to try and turn around on the fence, so I yelled at the white "cat" to move.
Well, when the "cat" turned it was an evil white opossum growling and coming at me. Surprisingly I kept my balance and didn't fall on the fence. I froze and after a few minutes of growing at me, it turned and walked away. This photoshop is dedicated to the demon opossum.
