Some 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 awhile, the customer returned to the office and said, "A long time. We're gonna build a house."
