When the milkman read the note he felt there must be a mistake. He thought she probably meant 1.5 gallons, so knocked on the door to clarify the point.

The blonde came to the door and the milkman said, I found your note to leave 15 gallons of milk. Did you mean 15 gallons or 1.5 gallons?

The blonde said, I want 15 gallons. Im going to fill my bathtub up with milk and take a milk bath to make me more attractive.

The milkman replied, Oh, OK. Pasteurized?

The blonde looked at the milkman with a confused look on her face and said…
No. Just up to my boobs.
