Two men in a pickup truck drove into a lumberyard. One of the men walked in the office and said, "We need some four-by-twos.
"The clerk said, "You mean two-by-fours, don’t you?"
The man said, "I’ll go check," and went back to the truck. He returned in a minute and said, "Yeah, I meant two-by-fours."
"Alright. How long do you need them?"
The customer paused for a minute and said, "I’d better go check".
After a while, the customer returned to the office and said, "A long time. We’re gonna build a house."
