She asks him, "Do you like what you see?"

The delivery boy says, "Yyyyyes"

The woman says, "I hear someone coming, get in here and close the door."

When the door was closed the woman opens her negligee and asks the delivery boy, "What part of me do you like best?"

The delivery boy says, "Your ears."

"My ears", the woman says, "but why?"

Well, said the delivery boy, a while ago you said that you heard someone coming. That was me."
