Two blondes, Kimberly and Mindy, were working on a house. Kimberly, 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.

Mindy, figuring this was worth looking into, asked, "Why are you throwing those nails away?"

Kimberly 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!"

Completely ticked off, Mindy yelled, "You're a real dipsh!t. The nails pointed toward you aren't defective! They're for the OTHER side of the house!"
