If your heat fails right now, it's an ALL-OUT CRISIS!  But at least you can feel better knowing THIS won't be the reason your heat goes out.  73-year-old Velma Kellen, of Yelm, Washington, just bought a brand new furnace, and had it installed.  BUT...it was NOT working right...her house NEVER got warm!  So, she called a repairman, who investigated and found out what the hell was wrong.  The furnace was working fine...there just happened to be a STRANGER living UNDERNEATH HER HOUSE!  The stranger messed with the ducts to REDIRECT them to keep HIMSELF WARM!  The repairman found empty beer cans and liquor bottles in the crawl space under the house.  The guy who was living there was not there at the time, and has not been back since.  It cost Velma $500 to get the ducts fixed.
