About 25 years ago, one of my coworkers had a feud going with another guy in our shop. He went and purchased a dumptruck load of gravel, he paid up front and gave very careful instructions about how he wouldn't be home and that the gravel was to be deposited in his driveway... please don't get any in the grass... don't make a mess... blah blah blah. He made it sound very good and up front... only he gave them the address of the other guy's house.

It cost him about $100 for the gravel, but he was quite tickled when the other guy arrived at home to see 4 tons of gravel blocking his driveway.
