Two Blondes With Hammers...
Lynn and 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 and 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!'
