Joke of the week
These two blonde carpenters are working on a house.
The one who's nailing down the timber keeps reaching into his nail pouch for nails and every time he pulls one out he either throws it over his shoulder or nails it in.
The other worker is intrigued by this and eventually asks him, "Why do you keep throwing those nails away?"
The first worker replies, "If I pull a nail out of my pouch and it's pointed toward me, then I throw it away because it's defective. If it's pointed toward the house, then I nail it in!"
The second blonde is amazed at the other guy's stupidity and yells at him, "You idiot! The nails pointed toward you aren't defective! They're for the other side of the house!"
