Reminds me of the story of two carpenters. One says, "Half of my nails
have the head on the wrong end." His partner responds, "You dummy,
those are for the other side of the house!"

And the other carpenters doing the other side of the house: "Damn, I
just cut this board too short." His partner replies, "Simple, just
turn it around and cut somemore off the other end..."
