Last year in the center of our pool, I found what appeared to be...how do I say this tactfully...hmmm...a large piece of poop (sorry, can't think of a tactful way to say it). I was FURIOUS! I fished it out only to find that it wasn't poop at all. It was a fried chicken leg.
I'm still trying to figure out how it got in there since we don't eat fried chicken.
