Little prick turfed my yard last night.

Thermite... put a half dollar size on his hood and light it with a magnesium ribbon, you have to light the magnesium with a torch. the thermite burns so hot it will go through the hood, engine block (if you have good aim you could probably hit that 4 banger) and will burn pretty good into the driveway... of course this is only for something a little more serious. another fun trick is putting it over the gas tank (run)
