Sale?

A well-stacked young advertising secretary wore tight knit dresses that
showed off her figure, especially when she walked. Her young,
aggressive
boss motioned her into his office one afternoon and closed the door.

Pointing to her tightly covered derriere, he asked, "Is that for sale?"

"Of course not!" she snapped angrily, blushing furiously.

Unchanged, he replied quietly, "Then, I suggest you quit advertising
it."
