Little prick turfed my yard last night.

Go to your local convienent store and buy a burrito in a bag, the kind you throw in the microwave. Wait your time, and when you find his car open, put the burrito under the passenger seat. Over the course of the summer the heat will make the burrito give off all kinds of interesting smells.

Another way is to sprinkle his car seats with powdered milk, and spritz them with water. THat sour milk smell lasts FOREVER!!!
