Two lady were working on a house.
One of them was nailing down siding. She’d reach into her nail pouch, pull out a nail, and either hammer it in or toss it over her shoulder.
The other lady, curious, finally asked, “Why do you keep throwing some of those nails away?”
The first one replied, “Well, if I pull out a nail and it’s pointed toward me, I toss it—obviously, it’s defective. But if it’s pointed toward the house, I nail it in.”
The second lady smacked her forehead and shouted, “You id!ot! The ones pointed toward you aren’t defective… they’re for the other side of the house!”
