This blonde heard that milk baths would make her beautiful.

She left a note for her milkman to leave 15 gallons of milk.

When the milkman read the note he felt there must be a mistake. He thought she probably meant 1.5 gallons, so he 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 1.5 gallons?"

The blonde said, "I want 15 gallons. I'm going to fill my bathtub up with milk and take a milk bath."

The milkman asked, "Pasteurized?"

The blonde replied, "No, just up to my tits."
