Two blondes were working on a house.
One, who was nailing down siding would reach into her nail pouch,
pull out a nail and either toss it over her shoulder or nail it in.
The other blonde, figuring this was worth looking into,
asked, "Why are you throwing those nails away?"
The first blonde explained, "If I pull a nail out of my pouch and it's pointed TOWARD me, I throw it away 'cause it's defective.
If it's pointed toward the HOUSE, then I nail it in!"
The second blonde got completely pissed off and yelled, "You ****!!! The nails pointed toward you aren't defective! They're for the OTHER side of the house!!"
