Dog Crapping Sign

Here is my rough draft on the dog crapping sign?

"To the brave dog owner who continues to allow their dog to defecate in my yard,

I sincerely hope that I catch you allowing your dog to crap in my yard. And when I do, I rain down on your home, car and yard with fecal matter like you have never seen."

I am open to any revisions or corrections that you deem necessary.

Here it is, I just took a picture.

And I know I don't have to convince any of you, but when I find this person, trust me, I will be saving up my own excrement to decorate their house with.
