A combination of the infamous "Upper Decker" and "Dry Dock". First, shut the flow of water off to the toilet by turning the valve on located low on the wall facing the back or side of the toilet. Then flush the toilet ensuring all the water gets flushed out. Then, remove the lide and defacate inside the tank and re install the lid. If you have a particularly large bowel movement or a partner you can defacate in the bowl as well for a traditional dry dock. This creates a highly concentrated sometimes lethal dosage of stink when the tank lid is removed so the tank can be inspected. Also known as the "Dry Deck". This should only be used in when absolutely neccessary. Or when staying at a freinds house.

Sometimes referred by the media as think tanks - A group of american people strongly allied with israel, nazism/zionism, and neo-conservatives who regularly create fresh lies (which they call spin) and deviant ideas about the world and all other civilizations. They do this to brainwash the naive TV junkie public who subconsciously will start to believe the lies if they hear the same stuff on a regular basis through various media outlets.
