Jane likes to take milk baths, but one day, she got in the tub and found that she didn't have enough milk. So she reached for her cell phone and called the dairy. The dairy said they'd send someone over right away.
She heard a knock at the door, knew who it was, but still called "who is it?"
"Milkman," she heard.
"Come in, it's open."
Milkman comes in. He's a new guy who doesn't know Jane. "Where are you?" he says.
"In the bathroom. Come on in."
He enters and sees Jane in the tub. Doesn't know what to say. Then says "Uhhhh . . . do you want your milk pasteurized?"
"No," Jane says, "up to my bosoms will be fine."
