Some guy bought a new fridge for his house. To get rid of his old fridge, he put it in his front yard and hung a sign on it saying: "Free to good home . You want it, you take it".
For three days the fridge sat there without even one person looking twice at it. He eventually decided that people were too un-trusting of this deal. It looked too good to be true, so he changed the sign to read: "Fridge for sale $50". The next day someone stole it.
