A blonde and a brunette drive into a lumberyard. The blonde gets out of her truck, walks up to a worker, and asks for some four-by-twos.

"You mean two-by-fours?" the worker asks.

The blonde says, "I’ll go check." She walks back to the truck, asks the brunette, and returns a minute later. "Yeah, I meant two-by-fours."

"All right. How long do you need them?" asks the worker.

The blonde pauses for a minute and says, "Hold on, I’d better go check."

After a moment, the blonde returns to the worker and says, "A long time. We’re gonna build a house."
