A woman hired a contractor to repaint the interior of her house. The woman walked the man through the second floor of her home and told him what colors she wanted for each room. As they walked through the first room, the woman said, "I think I would like this room in a cream color."
The contractor wrote on his clipboard, walked to the window, opened it and yelled out, "Green side up!" He then closed the window and continued following the woman to the next room. The woman looked confused, but proceeded with her tour. "In this room, I was thinking of an off blue." Again, the contractor wrote this down, went to the window, opened it and yelled out, "Green side up!"
This baffled the woman, but she was hesitant to say anything. In the next room, the woman said she would like it painted in a light rose color. And once more, the contractor opened the window and yelled, "Green side up!"
Struck with curiosity, the woman mustered up the nerve to ask, "Why do you keep yelling 'Green side up' out my window every time I tell you the color I would like the room?"
The contractor replied, "Because I have a crew of blondes laying sod across the street."
