Actually rotting potatoes stink far worse than rotting broccoli. The great part about the potato gag is they don't start to stink until it is too late, then the stink permeates the entire vehicle. Jam one under the drivers and passengers seat if in a hot sunny climate, they WILL rot in a couple of days. Throw a couple of slices of garlic baloney or a dead fish under there too. Spraying U.S. "Standard Bathroom Malodor" compound (yes this does exist and is the standard the US Gov't uses to determine stink levels) all over the place in most instances is enough to get the average person retching and Powr-Peukin' ! That stuff ROCKS !
The Upper-Dekker toilet trick (or the dry-docker, or the Old Faithful variations too) is another great one to pull on a beer-thievin neighbor...for those you would just have to come up with a reason to "use" (more like ABUSE) their bathroom.
Now I'm tawkin' STINK !

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
