Two blondes at a construction site Lynn & Judy were doing some carpenter work on a Habitat for Humanity House. Lynn was nailing down house siding, would reach into her nail pouch, pull out a nail & either toss it over her shoulder or nail it in. Judy, figuring this was worth looking into, asked, \- "Why are you throwing those nails away?" Lynn 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." Judy got completely upset and yelled, \- "You moron! Those nails aren't defective! They're for the other side of the house!"
