Dog Collar

This is to be used on a person who is very corporate and anal about their professional appearance. Find some dogshit and flatten it out between two pieces of wax paper until it is very,very thin. Use a razor to cut out pieces that are the exact size and shape of a collar-stay (plastic things that goin dress shirts to keep each side of the collar straight).When finished, place in the freezer overnight. Wake up when your target does and when he goes into the bathroom to shave, you run into his room and replace the plastic collar-stays with ones you made out of dogshit. If you are unsure of which shirt he is wearing, have some extras made to insert in all possible choices. They'll thaw out while he's at work or in class and he'll smell like shit.
