Carol and Donna were doing some carpentry work on a Habitat for Humanity house.

Carol, who was nailing down house siding, would reach into her nail pouch, pull out a nail and either toss it over her shoulder or nail it in.

Donna, figuring this was worth looking into, asked, "Why are you throwing those nails away?"

Carol explained, "When I pull a nail out of my pouch, about half of them have the head on the wrong end and I throw them away."

Donna got completely upset and yelled, "You moron! Those nails aren't defective! They're for the other side of the house!"
