Carpenters Clem and Jake were hired to reside a house. When Jake looked over at Clem, he saw him reach into his nail pouch, take out a nail, look at it, and throw it to the ground. Again Clem reached into the pouch, took out a nail, and threw it away. He kept doing this so Jake hollered over and asked what the (blank) he was doing. Clem answered "The heads on these here nails are on the wrong end! They're no darn good.". Jake yelled back "You big dummy, those nails are for the other side of the house!".
