How does this relate to partying? Well, if a few fluorescent lights, clattering keyboards, and yammering customers can flip off the honesty switch in a brain, think about what happens when that same brain enters a dingy liquor-soaked party house. If your digs look like they were decorated by Sid Vicious using the contents of his stomach, people will treat them accordingly. That "don't throw beer bottles directly on the ground" switch flips, and you wake up the next morning with a shattered-glass carpet.
Don't want anyone breaking bones in your precious living room? Don't leave a bottle of Everclear next to a pile of shot glasses and a Polaroid instant camera. Drunk people don't take direction, but they do take suggestions. A few empty trash cans, a clean carpet, and locks for all your handguns send a clear message your guests will appreciate. Leaving a bottle of tequila next to a pair of bicycles and two homemade lances sends an equally clear, much more entertaining lesson.
