A young man had engaged the services of a streetwalker, and had taken her to his apartment for the evening's revelry. However, she refused to undress until payment in full for her services was made in advance.
After some haggling, the young man agreed to her terms and he placed two crisp ten dollar bills in her hand. As soon as she had deposited the twenty dollars in her stocking, she bolted and started running down the stairs. The young man followed her into the street and chased her around the corner, yelling, "Stop, thief! Stop!"
The girl ran, and the young man stayed in hot pursuit, around corner after corner. He was surprised, finally, to find her waiting for him -not of her own accord, but firmly in the grip of a policeman who had heard his cries and had stopped the girl as she ran by. The officer asked:
"Is this the thief you were chasing?"
"Yes," replied the victim, breathless.
"I've been chasing her for blocks." "What do you want me to do with her?" the cop inquired.
The young man fought to regain his wind. "Do whatever you want with her," he answered. "It's already paid for."
