Ok so here's the story. I was sitting at my friends house about to have a smoke with him on mischief night and a suv drives by with kids in it. They turn around as i am sitting in my car and throw 2 shaving cream bombs the the driver side of my car. I'm pissed, and i fly after them and chase them down. I get the plate number and report them to the local police (what a good sameritain I am

haha) Anyway i get my friend and drive around for this SUV looking to get them back. We have no luck after about 1 hour and are about to turn in when we are driving on this street and my friend identify's the suv by a bumper sticker. Its sitting at the end of the driveway on a residential street.. So my friend and i go to the local quick-check to get something to put on the car...no eggs but there was chocolate pudding so we bought that and as im online waiting to pay i see this generic motor oil that is being sold for .99 a quart...so i buy 2 lol We go back to the house and throw the pudding all over the car along with the 2 quarts of oil, makeing sure not to miss a spot on the handles or windows...I find out the next day that it was this kid in high school who i know through another friend. This other friend tells me he is going to get my car back by putting saw dust in my exhaust...i have a new muffler that has fiberglass in the resonator...does saw dust have any possibility of messing my muffler up?
