Two blonde chicks were building a house together. One blonde was cutting the wood and the other was on a ladder nailing. Before hammering in a nail; the blonde on the ladder would reach into her nail pouch, look at it, and either toss it over her shoulder or proceed to hammer it into the wood.

The other blonde, confused, watched her do this and after she could take it no longer yelled up, Why the %@#& are you throwing some of the nails away?! Whoa! Dont yell! the blonde on the ladder explained, If its pointed toward me when I pull it out of my pouch, I throw it away. If its pointed toward the house, then I can use it safely! Duh!

The second blonde became irate at this point and started to call her all kinds of names, referencing how stupid she was and how she was the reason blondes get a bad rap for being dumb. She explained the importance of keeping all the nails, Dont throw away the nails that are pointed toward you! Theyre for the other side of the house! Duh!
