My builder mate was training his apprentice to lay some wood flooring.
The lad picked up a nail and saw it was upside down so decided to throw it away.
He carried on doing this.
My mate had enough and asked him what he was doing it for.
The lad said he was throwing away the ones that were upside down.
My mate was aghast. He said to him to not do it any more because they could be used for the ceiling.
