I call this "Death Mask of the Palmetto Bug".
Technically it is a former palmetto bug, having had its life ended by me a couple of years ago. I was home, alone, with a cast on my foot from major surgery, and the ill fated bug came into my bedroom. Getting up was a hassle, so I decided to live and let live-until the damn thing decided to fly and landed on my bare leg. I jumped up into my wheelchair and gathered up shoes to throw at it. I was so adrenaline charged from the effort (and from feeling competent even though I was crippled), I took a picture of it. Then I fiddled with the picture to relax. It's my avatar on at least one forum and is probably one of the most commemorated former palmetto bugs there ever was.
I suppose it's also technically and insect and not an animal but it IS an uplifting story. I was feeling week and tired, and getting up off my dead ass to kill the bug was energizing to me. Probably not so much for the bug, but hey, fame has its price.
