It’s as easy as BCC: Barricade, Concoct, Communicate.
Pile all of your furniture up against your front and back doors, along with any other additional entrances to your soon to be Alamo. Bust apart whatever furniture is left and cover the windows with spare wood and upholstery. Pile all scraps in the middle of your main staging area. This is where you may have to die, so if you die among the trash, you can be scooped up along with everything else for easy delivery to the nearest landfill.
This is where you contrive your plans to hold yourself hostage. It is also the execution phase, so moving on, you come to realize holding yourself hostage is a really bad idea because basically you’re just threatening the police to kill yourself and there is really no ransom to be had at all, so you’re going to have to pretend like someone else is in the house with you.
Call the police. Tell them you have been held hostage by an enormous man named Manuell Elberto Gero, and he wants forty five hundred thousand dollars in exchange for your safe return to your now destroyed home which you are already in. Manuell doesn’t know English that well, but he is trying his hardest anyway and the police are convinced that he will either get his money or kill you trying. Should they drop a duffel bag full of currency into your ventilation system, you’re free to hide the money in an unplanned yet highly convenient hiding place that the police, for whatever reason, will fail to search when going through your home trying to find evidence of Manuell’s escape route. Should they attempt to intrude on your beautifully orchestrated scheme to defraud taxpayers of next year’s new project budget to bulldoze a park, you’ll be forced to set fire to the scraps and tinder you have thrown into the middle of your living room floor. Should your scrap pile not make a large enough pyre to set fire to the ceilings, you’ll be forced to kill yourself by whatever means most immediately snuff your life force before the S.W.A.T. team comes around the last corner to see you naked and alone on the telephone. This way, they will not know that Manuell was but a figment of your imagination created as a ruse to stiff some dimwits out of a few thousand dollars at the expense of your freedom, dignity and even your life.
