John and I were putting the siding on a barn we were building. I noticed John would take nails out of his pouch, hammer in a few and throw a few away.
I asked him why he was throwing so many nails away. He said he was throwing them away because they had the heads on the wrong end.
I shook my head and said, "John! Don't you know anything about carpentry? Those nails are for the other side of the building!"
