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!'
