This is a story that my Dad told me about what his friend did to a neighbor across the street. The bad neighbor was very anal retentive about his yard, especially his lawn. The type of guy that was out there every day looking at it, grooming it, ect. The guy was a real jerk to those that lived near him along with his own family.
Now, my Dads friend was a bear of a man that is still alive, a world famous furniture maker and is still a bit of a hippie. Loved smoking pot, had a great family and could really give two shits about trival stuff, especially people that loved their garden over people.
One night, my Dads friend was high and had had a run in with the jerk across the street earlier in the day. At about 2-3am he went to his kitchen and got a large coffee tin (this was in the 80's), poked a ton of holes in it, added a looped string to the top, grabbed his post hole digger and walked across the street. He proceeded to carefully dig two dozen holes in the guys lawn. He would place the dirt in the coffee can, put the can in the hole and slowly pull up on the rope attached to the can while kind of shaking it so that it would create a soft earth mound which resembled a gopher mound. He did this to all 24 holes, now mounds.
In the morning he made his coffee early and sat out on his front porch, waiting for the jerk to get his newspaper. The jerk guy lost his shit, screaming about gophers. The jerk called exterminators and lawn care companies to deal with the issue and probably spent a good amount of money. My dads friend would wait for the lawn to be repaired and perfect again, he would then get high and do it all over again. He did this a few times up until the jerk fully ripped up his front yard, spending thousands of dollars. At that point my Dads friend got bored and moved on.
