Invite convicted criminals and former mental patients with violent tendencies
If the goal is to have both you and your family fearing for their lives, then this step is crucial and simply can't be skipped. Put a flyer up at your local high security prison advertising a free meal, and if you're lucky, a few recently released hardened criminals will come your way. Better yet, put a Craigslist ad searching for former mental patients that avoided serving sentences for murder by reason of insanity. The conversation at the dinner table is guaranteed to be unforgettable!
