J.S.
It's weird. I used to work at Bass Pro, (a hunting and fishing store), PETA came to protest it.
Soooo, some yahoo in a fish costume jumped in front of my car with his lovely little protest sign and almost became chopped tuna. Luckily I slammed on my breaks just in time, and barely missed him.
So, if I had run him down, I guess I could see a sign saying, "Oh here lies a slain fish...well, a guy in a fish costume anyway." Uggh, nutgall
ETA Nutgall! It's a typo but I like it.
