in a garbage bag mix the following: 3 sheets, soaked wtih water, preferably warm-hot, 1 dozen eggs, broken and dumped in the bag, 1lb of dog shit, 2lbs of cat shit, a three pound mixture containing 1 part shellfish, 1 part regular fish and 1 part sea food 'waste' (shells, guts, heads, poop lines from shrimp so on) and a gallon of vinegar just for that extra kick... now what you do is leave it outside for two days so the tempature kind of bakes all of it together, and also gets the most out of the mixture (but sealed tight so as to gather as little bugs as possible (they eat this mixture, you dont' want that) after two days put it in your closet and i garuntee you're parents won't smell whatever you smoke in your room, hell they probably won't even step 10 feet from your door...
