A few years back, one of my friends lived with his parents in a house with a rather long driveway that had a grass strip down the middle. So one night when another friend and I were sitting around bored, we decided that it would be funny to plant a tree in the grass strip. We acquired a tree, and planted it smack in the middle of the driveway.
The next morning, I received a phone call from the target saying that his father wasn’t impressed having to dig out a tree in the driveway on his way to work early in the morning. Note to self… always check working hours of others before playing jokes like that again.
