Cletus and Maynard were building a house together. Cletus was cutting the wood and Maynard was on a ladder nailing. Before hammering in a nail; Maynardwould reach into her nail pouch, look at it, and either toss it over his shoulder or proceed to hammer it into the wood.
Cletus, confused, watched him do this and after he could take it no longer yelled up, "Why the heck are you throwing some of the nails away?!"
"Whoa! Don't yell!" Maynard explained, "If it's pointed toward me when I pull it out of my pouch, I throw it away. If it's pointed toward the house, then I can use it safely! Duh!"
Cletus became irate at this point and started to call Maynard all kinds of names, referencing how stupid he was and explained the importance of keeping all the nails, "Don't throw away the nails that are pointed toward you! They're for the other side of the house! Duh!"
