a 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 anyone looking twice.
He eventually decided that people were too mistrustful of this deal.
So he changed the sign to read: 'Fridge for sale £50.'
The next day someone stole it!
They walk amongst us!
