Constructed of cardboard with a simple "Perv Box" writte on the side with a magic marker. The "This end up" arrow points downward. The Top of the box is open for admitees to step in and step out when they have taken care of their dirty minds and are functioning (Non-pervy) members of society again.
Person 1- "Umm, I has dirty thoughts"
Keeper of the box- "I sentence you to 20 minutes in the perv box"
