How about a dead skunk? I just got to fish one out of my neighbors duck pond, which had apparently been there 2 days or so.... nice and green tinged with mold and whatnot...... smelled pretty great, too. It didn't seem to bother the duck at all, I first saw it while the duck was ass-up next to it, and I was trying to figure out why there were TWO duck asses in the pond, before figuring it out. By pond, I mean high sided rubbermaid container sunk in the ground to playcate the duck while indoor water is changed and its area cleaned up. Easily the most exciting thing that's happened while I've watched peoples animals...
Someone to blame the pot on when the law shows up. Unless you killed them. In which case you should probably just take responsibility for the pot before they find the cadaver.
