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 upset and yelled, "You MORON! The nails pointed toward you aren't defective! They're for the OTHER side of the house!"
