Maybe it's me, but I find the concept of setting your own home on fire in order to get guests to leave to be not only rational, but bordering on brilliant. It beats the plan I often contemplate to get unwanted visitors out of my office, which is whipping my complimentary Rotary Club mug at their foreheads. I haven't tried it yet, but I'm fairly confident it would do the trick.
Where 46-year-old Dean Craig of Geneva, Ill. went wrong, in my opinion, is advising his guests in advance that he would set the house on fire if they didn't leave. (This probably elicited a response to the effect of, "Oh Dean, there you go, threatening to set something on fire again! Mind if we make some long-distance calls?") Instead, he should have excused himself to get more drinks, then ignited the kitchen while they weren't looking.
OK, you got me -- I stole that idea from Martha Stewart.
