Reminds me of when I was a kid. We had a neighbor, old people, that were so concerned about their grass. They would train their miniature dogs to shit on the side walk! They would yell at us kids for being on the sidewalk when going to and from school. Well one day I found some stuff my dad had to kill anything that grows (for use on concrete cracks and gravel surfaces) I snuck up to his house one night and poured the concentrated stuff in the words "fuck off" in his yard, big and bold. They were very displeased and since they were mean to every kid in the hood they couldn't figure out who did it. They tossed out grass seed, of course it didn't grow. They tried sod, that died. lol they were stuck with that for years.
