A couple of blonde men in a pickup truck drove into a lumberyard. One of the blonde 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 a minute later and said, "Yeah, I meant two-by-fours. "All right. 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."
