A builder was going through a house he had just built with the woman who owned it.

She was telling him what color to paint each room.  

They went into the first room and she said "I want this room to be painted a light blue."

The builder went to the front door and yelled "GREEN SIDE UP!"

When he went back into the house, she told him that the next room was to be bright red.

The builder went to the front door and yelled "GREEN SIDE UP!"

When he went back into the house, she told him that the next room was to be purple.

The builder went to the front door and yelled "GREEN SIDE UP!"

When he came back, the lady was pretty curious, so she asked him, "I keep telling you colors, but you always go to the front door and yell GREEN SIDE UP!

What's that for?"

The builder said, "Oh don't worry about that, I just have a couple of blondes laying the sod out front."
