Three friends were walking around town when they came across a prostitute soliciting on a street corner. Attracted by her good looks, they inquired about her rates. “Actually I operate on a sliding scale,” the hooker said. “You see, I charge $10 an inch.”
The men accepted and went off to her apartment, where they took turns with her. Later the first guy proudly told his pals that he’d paid $70. The second boasted that he hadn’t received any change from a $100 bill.
