Some guys in a pickup truck drove into a lumberyard. One of the men walked in the office and says, "We need some four-by-twos."
The clerk replies, "You mean two-by-fours, don't you?"
The guy scratches his head and says, "I'll go check," and goes back to the truck.
He returns and says, "Yeah, I meant two-by-fours."
"All right. How long do you need them?"
The guy pauses for a minute and says, "I better go check."
After a while, he returns to the office and says, "A long time. We're gonna build a house."
