Two female blonde carpenters were working on a house. One blonde was
on a ladder nailing. She'd reach into her nail pouch, pull out a
nail, look at it, and either toss it over her shoulder or proceed
to
nail it into the wood.
The other blonde couldn't stand it any longer and yelled up, "Why are
you throwing some of the nails away?"
The first blonde explained, "When I pull it out of my nail pouch, if
it's pointed toward me I throw it away. If it's pointed toward the
house,then I can use it!"
The second blonde got really excited and called her all kinds of
names, explaining, "Don't throw away those nails that are pointed
toward you! They're for the other side of the house!!"
