The proprietor of an adult store steps out to run a few errands and leaves his employee in charge. A woman comes in and wants to purchase a dildo. She looks at the shelf behind the register.

''How much for the white one?''

"$10."

''How much for the black one?''

''$20." She buys the white one. A little later , another woman comes in and also wants to buy a dildo. After asking the clerk for prices, she decides on the black one. A third lady comes in for a dildo. She checks the price of the white one , the black one and asks about the plaid one. She makes her purchase and leaves. The proprietor returns and asks how things went.

"Great! I sold a white one, a black one, and I got thirty buck for your thermos!"
