A pickup with three guys in it pulls into the lumber yard. One of the men gets out and goes into the office.
"I need some four-by-two's", he says.
"You must mean two-by-four's" replies the clerk.
The man scratches his head. "Wait a minute," he says, "I'll go check."
Back, after an animated conversation with the other occupants of the truck, he reassures the clerk, that, yes, in fact, two-by-fours would be acceptable.
"OK," says the clerk, writing it down, "how long you want 'em?"
The guy gets the blank look again. "Uh... I guess I better go check," he says.
He goes back out to the truck, and there's another animated conversation. The guy comes back into the office. "A long time," he says, "we're building a house".
