Years ago had a guy in the neighborhood who would leave for work early each day. He has a very fast but loud car which he would rev up 6-10 times before leaving the driveway waking up everyone. Took a c****m and put a couple spoonfuls of talcum powder in it. Rolled it over his exhaust pipe I really hope he got a mile away before the c****m blew up and all he saw was what looked like smoke coming out of his exhaust. Just loved the image of him thinking he blew something.
