Replying to Vandalism at school

theres this kid at our school whos got way to much money, & makes a total ass out of himself all the time, so one of my buddies took things into his own hands and drew giant red penises on both sides of this kids car and on the hood during the schoolday. mind you that they were drawn with window paint that can easily be wiped off with your hand (we wouldnt want to fuck up this kids new porsche after all, now would we). this little bitch decides taht instead of wiping off the cocks, hes going to get the principle and show it to him. now our entire class is going to lose the right to park at school unless my buddy fesses up, which hed better not. what the fuck is wrong with this kid, why not just wipe them off instead of making everyone ride the bus to school and back?
