Things Not To Do At A Hostage Negotiation As Hostage Taker:
Demand to speak only with FBI agents Fox Mulder and Dana Scully.
Have one of the hostages hold your gun while you make a quick trip to the bathroom.
Let one hostage go to the bathroom. When he doesn't return, send the others to see what's taking him so long.
Agree to let the hostages go, after doing so, make you demands.
Rig the building to explode if someone tries to go through the door, then remember that you forgot to lock your car and leave the room.
Confuse the detonator for your explosive booby-traps with your garage door opener.
Tell the negotiator that you'd rather choke on tear gas than let the hostages go.
Allow one of the hostages to win possession of your gun because of a paper-rock scissors tournament.
Forget your gun at home.
Run away bawling like a baby when one of your hostages calls you a "meanie".
Ask the negotiator to tell your fiancee that this is all a joke and would she marry you.
