Seamus and Paddy drove into their local timber yard. …. … Paddy walked into the yard office and said, “We need some four-by-twos.” …. …. The storeman asked, “You mean two-by-fours, don’t you?” …. …. Paddy said, “I’ll go check,” and went back to the truck. He returned and said, “Yeah, I meant two-by-fours.” “All right. How long do you need them?” asked the storeman. Paddy paused for a minute and said, “I’d better go check.” After a while, he returned to the lumber office and said, “A long time. We’re gonna build a house.”
