A polack goes into a hardware store and tells the sells clerk "I need some 4 by 2's." The sells clerk asks, "Do you mean 2 by 4's?" The polack says, "Hold on a second." He goes outside for a moment then comes back in and says, "Yes, that's what I need, some 2 by 4's." The clerk asks him, "How long do you need them?" The polack says, "Hold on a second." and goes back outside for a moment upon returning he says, "We need them a long time. We're building a house."
